Report: 65% of US adults now use social networking sites, up from 7% a decade earlier
Andrew Perrin / Pew Internet :
Context & Ripple Effects
Pew's Andrew Perrin puts a number on what had been anecdote: 65% of US adults now use social networking sites, up from 7% a decade earlier — the moment social stops being a young-skewing niche and becomes a default adult medium. The follow-on coverage shows what a mass audience does next: within two years Pew finds 55% of Americans 50 and over getting news on social platforms, a cohort that barely registered in the 2005 base, per its 2017 study of news use on social media.
The arc matters for publishers and platform strategists alike: once adoption is near-universal, competition moves from signing users up to owning their habits — and the same Pew series later shows half of Facebook news users relying on that single platform for news.
First-order effects
- Social platforms become a mainstream distribution surface overnight: with roughly two-thirds of adults reachable, any publisher, advertiser, or campaign built for TV-and-web audiences must treat feeds as core inventory, not experimental spend.
- Pew's own research agenda shifts with the audience — from measuring 'who uses social media' to measuring what they do there, which is exactly where its dating-app (usage among 18- to 24-year-olds nearly tripled since 2013) and news-consumption studies head next.
Second-order effects
- News consumption consolidates around the biggest networks: Pew's later finding that 26% of adults get news from two or more social sites — and that half of Facebook news users get news via Facebook alone — forces outlets to optimize per-platform rather than for the open web, concentrating referral power in one or two companies.
- Advertisers gain a single channel covering most of the adult population, which pressures non-social digital properties on price and pushes older demographics — the fastest-growing news-on-social segment — into ad targeting they were previously insulated from.
Third-order effects
- The growth story ends before the power story does: Pew's own follow-up shows internet, smartphone, and social-media usage plateauing (69% for social) after 2016, meaning future platform competition is zero-sum for attention rather than additive for users — a structure that favors incumbents with entrenched news and social habits.
- If single-platform news reliance keeps rising, gatekeeping of public information effectively migrates to a handful of private companies, setting up the regulatory and trust debates that dominate the sector afterward.
The trend: US social media moved from niche adoption to near-saturation in a decade, shifting the industry's battleground from user growth to control of news distribution and daily habits.
