The ad-supported internet is today responsible for more than 10.4 million jobs in the U.S., roughly twice as many since 2012 and 3x as many since 2008, according to the Interactive Advertising Bureau's latest study.

While the majority of companies that spur those jobs lie in 5 key market areas (San Francisco Bay Area, Manhattan, Virginia's Arlington County, Boston's Route 128, and Seattle/Tacoma), 86% of the jobs those regions create lie outside those centers of internet industry concentration. Silicon Valley, specifically, only accounts for 4% of jobs related to the commercial internet.

Why it matters: These figures offer a small snapshot of how the Internet boom has played out beyond Silicon Valley and other coastal hubs. The study shows that ad-supported internet jobs are prevalent in every U.S. Congressional district, with some of the biggest numbers of jobs in conservative-leaning and swing states like Florida, Texas, North Carolina and Pennsylvania.

Chief Justice John Roberts was hospitalized overnight after a fall on June 21, a Supreme Court spokesperson confirmed to the Washington Post on Tuesday.

The CEOs of tech's four leading giants will defend their industry's growing concentration of power from critics on both right and left who view them as monopolists when they testify, most likely virtually, before Congress on July 27.

Why it matters: The joint appearance by Facebook's Mark Zuckerberg, Apple's Tim Cook, Amazon's Jeff Bezos and Google's Sundar Pichai will mark a historic collision between the leaders of an industry that has changed the world and political leaders who believe those changes have harmed democracy and individual rights.

Why it matters: Storylines in Trump's populist sweet spot that carried the news cycle for much of his presidency — immigration, trade, a strong economy — have fallen away during the pandemic.
