Social Media Consumption: Extrapolations


ASK
Extrapolate to 2050:
Individual daily consumption of all media (web-based and traditional)
Individual daily consumption of social media

All Media

Zenith (a media agency) tracks this info on a global scale (I’ve not found other sources). They’ve only been publishing reports for the last four years, but I found a Recode article that interviews the head of forecasting at Zenith (Jonathan Barnard). This article provides historic data back to 2010, and forecasts to 2019, contrasting North America with the global average. The article was published in May 2017, and Zenith published a new report in 2018 with slightly different data for the last few years and looking forward, but the most recent report does not provide the context of the previous 10 years. For consistency of methodology, I’ve just used the data quoted by Recode for the following extrapolation.

[Excerpts from all four published Zenith reports are below, showing the yearly revision to their data. In summary, the estimates become more conservative with each subsequent report up until the latest report, which shows a jump again.]

Here are excerpts from the press releases for the annual “Media Consumption Forecasts” by Zenith.

From the 2018 Report:
2018: 479 minutes per day consuming media
12% more than in 2011
2020: 492 min/day

From the 2017 report:
2019: less than 1% growth
2017: same as 2016
2016: 456 min/day
2010: 411 min/day

From the 2016 report:
2018F:448 min/day
2015: 435 min/day
2010: 403 min/day

From the 2015 report:
2017F:506 min/day
2015: 492 min/day
2014: 485.3 min/day
2010: 461.8 min/day

Social Media

eMarketer and Statista both provide estimates of daily social media consumption. The eMarketer figures cover the US, and the Statista figures are global.

Upon first inspection of the data, the Statista figures seem to be roughly 3X higher than eMarketer’s figures, a disparity that does not agree with my understanding of the variation by country (see We Are Social chart below). I’m quite confident that Statista’s data actually comes from marketing firm Global Web Index, and their recent report (which does not include all the historic info available at Statista) makes frequent passing reference to the increasing amount of time users are watching video on social platforms. In reading various qualitative discussions of social media use, I find many sources group YouTube and Facebook minutes of use together under the social category.

When eMarketer’s social and video minutes are combined, they come in closer range to Statista’s figures, so I believe this is a good rough approximation.

Here’s the extrapolation for both eMarketer (combined social and video) and Statista:

daily-social-media-consump-extrap-2050-US-global

Note: The trendline of best fit for most of our extrapolations doesn’t fit the eMarketer data very well, so instead I’ve used a power trendline. The polynomial(2) trendline we often use does fit the Statista data pretty well, however. (You see both in the figure above)

I also noticed in reading qualitative discussions that Facebook and YouTube’s average daily minutes are very similar, with video getting a bit more time, and this is also the shown in eMarketer’s data, with the gap slowly widening in video’s favor. I’ve extrapolated eMarketer’s social and video figures separately to show how that divergence might take shape (again, the power trendline seemed to fit best).

daily-social-media-video-consump-extrap-2050-eM

No surprise to see video pulling ahead of social, and I’m certain that marketing research focused on the growth of online video would suggest a much steeper curve.

Meanwhile, and also no surprise, here’s a chart (from Recode, citing Zenith) showing that Internet consumption is overtaking traditional TV consumption (from the same source as the Global/N.American overall media consumption figures above).

Zenith-recode-tv-vs-internet-2010-2019
[Click through to the great interactive version at Recode.]

Another ad media firm, GroupM, also predicts online time overtaking traditional TV this year.

In line with that, this year (2018), globally, advertisers are expected to spend more online than on television for the first time. Interestingly, social media ad spending is expected to rise 21% to $58 billion while video ad spending is rising 19% to $32. (Recode citing Zenith)

Here’s a snapshot from We Are Social showing how social media consumption varies from one country to another in 2017.

Note:
eMarketer aggregates data from various research firms and they don’t offer much detail (at least, not to unpaid customers). I don’t know if these figures are based on consumer surveys or if they are based on data provided by service providers.

Statista (citing ??, 2017), 2018

Note:
Statista does not give the name of the original source (to unpaid customers), but they do specify that this data is based on worldwide, online consumer surveys of adults aged 16-64. Statista also reports that the survey question asks, “Roughly how many hours do you spend engaging with/connected to social networks or services during a typical day?” The source must be GlobalWebIndex, which conducts web-based surveys. Their latest report (2018) estimates current social media time exactly as reported by Statista. Their press release here describes the same survey question, and the same survey audience (16-64 year olds).

Entrepreneur, in Jan 2018 (date established via InternetArchive), published the following comparative daily consumption figures:
youtube: 40min/day
facebook: 35min/day
Snapchat: 25min/day
Instagram: 15min/day

“The way that people consume media will continue to change,” said eMarketer’s UK analyst, Bill Fisher. “Many traditional habits are simply transitioning over to digital devices and platforms, while digital-only habits continue to proliferate. However, what’s apparent from this forecast is that UK adults have reached a plateau. While the media mix may ebb and flow, and it will increasingly flow toward mobile, adults’ media consumption capacity has reached its peak.”

Comscore is tracking differences between desktop and mobile internet usage.

CC’s note: Not sure if historic data are aggregated, but here’s a sample of recent statistics (covering US, Canada, France, Germany, Italy, Spain, UK, Argentina, Brazil, Mexico, India, Indonesia and Malaysia)

Smartphones are the dominant platform in terms of total digital minutes, in every region Comscore examined.
Most pronounced in India – 89% total minutes
Least noticeable in Canada – 43% of total minutes (42% desktop, 15% tablet)
US: 60% (30% desktop, 10% tablet)

Mobile minutes are overwhelmingly spent with apps – over 80%

Top apps (everywhere, in various rankings) include:
Google Search, Whats App, Facebook, YouTube, Google Play, FB Messenger

Three largest categories where digital time is spent:
Multimedia (includes several large video streaming services), Social Networking, Instant Messengers

Looking specifically at mobile digital time, the top four categories are:
Entertainment, Social Media, Instant Messaging, and Games

On average, Social Media has the largest average share of mobile minutes, but Entertainment is larger in the US and Canada.

Among Social Media apps, Facebook, totally dominates, followed by Instagram, then Snapchat, then Twitter (Twitter’s share is tiny).

Among Messaging apps, WhatsApp totally dominates, then Facebook Messenger (less than half), then WeChat (very small share).

The report includes visualization of platform preferences for certain categories. Business/Finance (which includes banking) shows the most even split between mobile and desktop reach. In the majority of markets, retail is heavily biased toward mobile. News/Information is overwhelmingly biased toward mobile.

(shown for UK and India – both show a fairly even split between desktop and mobile for banking minutes).

The report also includes visualization of subtle seasonality in certain categories of content (shown for UK and Brazil).

Whole-Day Time Allotment


ASK: Historic trends in time allotment? Global data?

SUMMARY

The Bureau of Labor Statistics has conducted the American Time Use Survey (ATUS) annually since 2003. This is the first federally funded, rigorous time use survey, although other large scale surveys have been conducted in the mid 20th century. Smaller scale time-use diaries were also collected going back to the early 19th century. Much of this data is US-specific, but the UN has aggregated time-use surveys into regional categories.

FINDINGS

Wall Street Journal, in 2016, created some nice, interactive graphics illustrating the changes reflected in the ATUS from 2003 through 2015.

ATUS-2003-2015-WSJ

[Click for larger. Visit source for interactive version]

Excerpt:

Americans overall are working less and sleeping more than they were a decade ago, trends that point to an aging population and fewer people in the workforce. But among those who have a job, people are working more. And in general, men spend more time than women on leisure activities, while women sleep about a half-hour more each day.

Additional charts at WSJ show breakdown by sex, employment status, age, and whether children are in the home.

Global aggregation of time-use surveys

United Nations Development Programme, 2015
“Time Use Across the World: Findings of a World Compilation of Time Use Surveys”

Paper is based on 102 time use surveys carried out in 65 countries. It gathers as many time use survey data and metadata as possible, and builds synthetic indicators on time use across the world, based on this data set. One of the main goals of the paper is to highlight time-use differences between men and women, particularly the inequities between paid work and unpaid work. To that end, most of the charts are divided by gender, with only a single chart showing gender-neutral time-use averages (that one chart is for the Mid East and Northern Africa region). In the case of Europe, the charts are further segmented by west, north, and southern Europe.

Survey data are aggregated into the following broad regions:
Middle East and North Africa (9 countries, 10 surveys)
sub-Saharan Africa (8 countries, 10 surveys)
Asia (9 countries, 13 surveys)
Latin America (7 countries, 8 surveys)
Europe (15 countries, 29 surveys)
Transition [Eastern European countries with Soviet history] (12 countries, 12 surveys)
North America (2 countries, 14 surveys)
Other developed countries (3 countries, 6 surveys)

The following chart shows which countries are included in those categories, and highlights which countries have conducted repeated surveys.

Akamai offers the following commentary on essentially the same historic data, also from Ericsson (emphasis mine):

Mobile data traffic has continued to grow, and Figure 39 shows total global monthly data and voice traffic from the first quarter of 2012 to the first quarter of 2017. It depicts a continued strong increase in data traffic, with voice traffic growth having diminished to the low single digits per year. The growth in data traffic is being driven both by increased smartphone subscriptions and a continued increase in average data volume per subscription, fueled primarily by increased viewing of video content. In the first quarter of 2017, data traffic grew nearly 12% quarter-over-quarter and nearly 70% year-over-year. Looking at the full five-year period shown in Figure 39, cumulative voice traffic growth was 28%, while cumulative data traffic growth was more than 1,200%.

Ericsson survey results and commentary on the expectations for 5G enabling VR/AR mobile applications:

Video now accounts for over 50 percent of all mobile traffic – a figure that is expected to increase to over 75 percent by the end of 2023.

A recent survey* of consumers aware of VR in 8 countries suggested that 7 out of 10 early adopters expect VR/AR to fundamentally change everyday life. These early adopters expect 5G to play a significant role in enriching the shared VR experience by providing lower latencies, haptic feedback and higher resolutions.

In its current forms, AR may be much more suited than VR to mobile applications. However, the line between the two is already dissolving, with merged reality (MR), stereoscopic six degrees of freedom (6DoF) and holographic video on the horizon.

Ericsson: 5G impacts on sports events


Alongside November 2017’s Mobility Report, Ericsson offered some speculations on the effect 5G mobile service might have on sporting event spectators.

Excerpts:

Key findings

    Growth in mobile traffic at events can be attributed to changes in user behavior, especially among younger people
    Spectators now mainly share or stream live videos and engage with social networks at events, as well as increasingly creating and uploading their own content
    Augmented reality (AR) and virtual reality (VR) technologies can enhance visitors’ and remote spectators’ experience of events, making them available in new ways
    4G systems will continue to support event visitors with services, but in the near future, 5G technology will have the capability to transform their experience
    At future events and connected venues, with high traffic density and increasing use of demanding services such as AR and VR, proactive management and automation will be essential to meet committed service levels

A range of services may be included in 5G showcases, allowing venue visitors to turn from spectators into participants and enabling them to:

    Watch events from different viewpoints with interactive control
    Access multiple cameras filming an object to achieve a 3D view
    Experience sports activity from the perspective of the athlete via mini-cameras
    Enjoy an in-stadium experience outside the venue through haptic or tactile feedback
    View live holographic projections of athletes
    Integrate supplementary content into their live streams
    See athlete, event or venue statistics superimposed on their device display
    Analyze and display performance data through sensors embedded in sports equipment
    Receive real-time information on factors such as the speed and location of a ball
    View overlay and substitution content, for example, explaining rules, giving more details and personalizing the experience

Social Media Users


Hootsuite and We Are Social publish an annual report detailing internet use and social media growth. In their 2018 report, they list the most active social platforms (slide 59), led by Facebook (2,167B MAUs), with WeChat at #5 (980M MAUs). Because Facebook is still not used in China (not broadly), we have added the Facebook and WeChat user figures to roughly approximate the number of people using social media. At 3.147B, this comes very close to the report’s estimate of active social media users (3.196B).

100% Internet Penetration


ASK: Forecasts for global 100% internet users?

FINDINGS:

eMarketer publishes a ~5-year forecast of internet penetration every year. It’s most recent publicly accessible forecast showed a downward revision from the previous year’s forecast.

As of June 2016
2014 41.1%
2015 44.3%
2016 46.8%
2017 49.0%

2019 50.6%
2020 52.2%
2021 53.6%

src: eMarketer, April 2017

This is the only significant forecast I’ve found for this indicator.

*

The International Telecommunications Union tracks internet users as a percentage of the global population. Historic data is available back to the mid 1990s.

I’ve added a trendline projection, which suggests ~2030 as a possible saturation date.

global-internet-users-ITU-2017-extrap-2030

However, when eMarketer’s most recent forecast figures are added, the trendline wiggles. The same type of trendline (2nd order polynomial) then delays saturation until 2040.

global-internet-users-ITU-2017-extrap-2030-emktr-2nd-poly

Adjusting the trendline type (to a 5th order polynomial) gives a better R-squared value, and again brings saturation back to ~2030.

CC’s NOTE: In 2048, the UN medium fertility variant projection for world population is 9.7 billion. At 7.6 billion users, that would be about 78% of the projected 2048 population. That would be a big jump from the 26% of global population FB users accounted for in 2017, but still not literally everyone.

Proliferation of cell sites and light bulbs


cell-sites-vs-light-bulbs2

NOTE:
This chart reflects production of large incandescent lamps, which include the ordinary electric-light bulbs for residential, commercial, and industrial use. This category excludes miniature lamps such as those for motor vehicles, flashlights, and Christmas trees. (Bright, p.5, Note 2). Production of other types of lamps (miniatures, photofloods, etc) seem to’ve been fairly low in the first three decades of lamp production (1891-1919), but began to ramp up soon thereafter, certainly by 1939 (figures reported in Bright, p. 10), and by 1945 these other categories of lamps accounted for about 36% of total lamp production (calculated based on figures reported by the FTC in 1980, p.34).

Table 111-1 shows the U.S. value of shipments, exports, and imports in SIC 3641 for the years 1967 to 1973. During that time; imports never accounted for more than 6.79 percent of total domestic value of shipments while exports never accounted for more than 5.21 percent. When imports are added to value of shipments and exports subtracted from the whole, consumption can be found. Between 1967 and 1973, 93 percent of the total lamps consumed in the United States were manufactured in the U.S. In the same seven-year period, 94.8 percent of the lamps manufactured in the United States were used in the U.S.

[p.74]
Note: According to CTIA, there has been an approximate 57 percent growth in the number of cell sites over the last ten years (in 1986, there were 1,531 cell sites in service).

The report notes that, according to CTIA, the number of cell sites will significantly increase as the mobile wireless industry densifies and prepares for 5G. Also, because multiple cell sites can be co-located in the same “tower” site, the reported cell sites should not be equated with “towers.” The reported cell sites include repeaters
and other cell-extending devices (e.g., femtocells or distributed antenna systems).

A specialized communications tower industry has developed to provide and manage the
support structures for the cell sites. Today, there are more than 120 tower and DAS operators in the United States, and a majority of towers are now owned or operated by independent companies rather than by mobile wireless service providers.142 Independent tower operators own, operate and lease shared wireless communications and broadcasting towers, manage other tall structure sites (such as rooftops and water towers), and to a lesser extent, own and operate neutral facilities to host small cells and DAS networks for mobile service providers.

(Although 2019 phones will be advertising capacity, even if there’s no network to connect to right away.)

“I believe that eventually consumers will pay for just one broadband connection, fixed and mobile. When I say 50M or more homes, I mean wireless substitution. I think you can draw a parallel with local telephone service and long distance. The long distance business evaporated. Similarly, today’s fixed and mobile broadband services will collapse into one. The cellular operators today are better positioned to take that market.” Peter Rysavy (wireless technologies consultant)

Network World, Mar 2018
“Submarine cable boom fueled by new tech, soaring demand”

Excerpts:

Between 2013 and 2017, the subsea cable industry has added an average of 32 percent of capacity annually on major submarine cable routes.

SubTel Forum projects global submarine cable capacity will increase up to 143 percent between 2017 to 2022, and it also notes that a construction boom is already underway. Last year, 62,000 miles of submarine cable was added globally. This, after global averages didn’t crack 19,000 miles of added cable between 2013 to 2016.

According to TeleGeography, the international capacity deployed by companies such as Google, Facebook, Microsoft, and Amazon rose 14-fold between 2012 to 2016. … By investing in them, these mega-companies get them built faster. They also get a level of control over construction, maintenance and operation that’s ultimately more economical than becoming a paying customer on a telecom’s cable.

[It’s now cheaper to build systems with greater bandwidth. In 2013, new systems averaged 9 terabits per second (Tbps) — multiple systems planned for 2018 and 2019 will have capacities of 60 Tbsp. Tech advances are also eliminating costly and complex infrastructure layers, such as regen equipment. In addition, new cables can land directly inside multi-tenant data centers, rather than a traditional cable landing station (CLS) on the beach.]

Telegeography, Nov 2017
A Complete List of Content Providers’ Submarine Cable Holdings

This article lists cables owned or strongly supported by Amazon, Facebook, Google, and Microsoft.

Excerpt:

The amount of capacity deployed by content providers has outpaced all other customers of international bandwidth in recent years. Between 2012 and 2016 the amount of international capacity deployed by companies like Google, Facebook, Microsoft, and Amazon has risen 13-fold to 179 Tbps. (In contrast, international capacity deployed by all other operators only rose threefold, to 272 Tbps).

Content providers prioritize some submarine cable routes more than others in their network deployments. Between 2012 and 2016, content provider demand was the strongest across the Atlantic where capacity rose at a compound annual rate of 66 percent to 42 Tbps.

And as such, the largest content providers have built U.S.-centric network architectures. Their investments on systems directly connecting Europe to Asia are almost non-existent, in comparison. In the Atlantic and Pacific, content providers accounted for over half of total demand in 2016. In contrast, content providers represented only a small share of capacity usage on routes connected to the Middle East and Africa.

Submarine Telecoms Industry Report 2017

Excerpts:

Submarine fiber systems ownership
2013-2017: 61% private, 39% consortium
2018 and beyond: 83% private, 17% consortium

A recent trend towards private ownership has been observed compared to historical trends of primarily consortia ownership. Business cases for smaller systems have been prevalent, and the demand driving these systems has differed from years past. Globe-spanning infrastructure cables that require consortium ownership have fallen out of favor, contributing to this trend shift.

The boom of private ownership will continue to extend well into the future, as more niche and point-to-point systems are implemented. Much of this is driven by intra-regional needs — typically for smaller nations looking to get connected. However, a growing number of systems are being driven by factors not previously seen in the submarine fiber industry.

China & India Urban Residential Floor Space in 1993, 2002, 2008
china-india-floor-space-93-02-08

Excerpt:

Average income growth has been a key reason behind these different trends in the quality of the housing stock. The urbanisation process in China has transferred large numbers of workers from relatively low productivity jobs in the rural sector to higher productivity jobs in urban areas. This movement has been a driver of the rapid growth in incomes in China over the past three decades, which has far exceeded the growth in incomes in India (Graph  7). Over time, Chinese households have chosen to spend their higher income on higher quality dwellings and dwellings with larger floor space and, as a consequence, the share of concrete dwellings and residential floor space per capita has increased.
