The findings from comScore's latest study highlight three of the fastest-growing mobile market trends:

  • E-commerce: Letgo (3), OfferUp (2), Flipp (4), Venmo (5) and Wish (7), are facilitating real-world marketplace transactions
  • Travel: Uber (6), Waze (8) and Lyft (9) all help users travel from one point to another via auto
  • Social connectivity: Tinder (10), Bitmoji (1) and GroupMe (11) all facilitate gatherings and social interaction

Why it matters: As comScore identified last year, we are now at or nearing "peak app" usage, meaning that most smartphone users download zero or only one new app per month. Thus, selectivity around app downloads illuminates trends that represent a major shift in the internet economy. Before smartphone app usage came to dominate mobile time spent, consumers mostly used the internet to bring real-world interactions online, like dating, mail and shopping. The rise of these three mobile app trends show how much the app economy is moving towards improving real-world engagements, like car travel, group get-togethers, and local commerce selling/trading.

The story of American businesses in the coronavirus pandemic is a tale of two markets — one made up of tech firms and online retailers as winners awash in capital, and another of brick-and-mortar mom-and-pop shops that is collapsing.

Why it matters: The coronavirus pandemic has created an environment where losing industries like traditional retail and hospitality as well as a sizable portion of firms owned by women, immigrants and people of color are wiped out and may be gone for good.

Millions of angry gamers may soon join the chorus of voices calling for an antitrust crackdown on Apple, as the iPhone giant faces a new lawsuit and PR blitz from Epic Games, maker of mega-hit Fortnite.

Why it matters: Apple is one of several Big Tech firms accused of violating the spirit, if not the letter, of antitrust law. A high-profile lawsuit could become a roadmap for either building a case against tech titans under existing antitrust laws or writing new ones better suited to the digital economy.

Survey: Fears grow about Social Security’s future

Data: AARP survey of 1,441 U.S. adults conducted July 14–27, 2020 a ±3.4% margin of error at the 95% confidence level; Chart: Naema Ahmed/Axios

Younger Americans are increasingly concerned that Social Security won't be enough to wholly fall back on once they retire, according to a survey conducted by AARP — in honor of today's 85th anniversary of the program — given first to Axios.

Why it matters: Young people's concerns about financial insecurity once they're on a restricted income are rising — and that generation is worried the program, which currently pays out to 65 million beneficiaries, won't be enough to sustain them.
