Silicon Valley giants like Facebook, Twitter and Uber have for some time been subjects of books, movies and long exposés—and now it's YouTube's turn, with a new book deal for Bloomberg journalist Mark Bergen's "Like, Comment, Subscribe."

Why it matters: “It’s a technical and cultural story that hasn’t been told in its entirety yet,” says Bergen when asked why he chose that particular star in Alphabet-Google’s constellation.

  • He adds that people are increasingly interested in understand the technologies that are deeply shaping their internet lives — making YouTube and its video recommendation algorithm prime subjects to dive into.
  • YouTube, like its peers, is wrestling with questions of free speech and governance of the internet.
  • YouTube is also a potential target of the growing antitrust probes into Big Tech, a topic Bergen says will be a "fun question" to explore through his reporting. (Though he adds he doesn't believe breaking YouTube off from Alphabet-Google would ever happen.)

The big picture: Bergen’s book is the latest in a long list of projects in the last year or so chronicling the tech industry’s bad behavior and reckoning with the dark side of its influence.

  • Others whose stories have become subjects of books include Uber, WeWork, Instagram, Tesla, and Facebook.
  • Bergen's book, which will be published by Viking, has no release date yet.

Joe Biden's campaign released his 2019 tax returns on Tuesday, showing that he and his wife, Jill, paid nearly $300,000 in federal taxes last year.

Why it matters: The release, timed just hours before the first presidential debate, comes days after a bombshell New York Times report said that President Trump paid only $750 in federal taxes in 2016 and 2017. Biden's team is hoping to make the tax contrast a sticking point during their showdown.

New York City's coronavirus positivity rate has ticked up to 3.25%, its highest since June, Mayor Bill de Blasio said at a news conference on Tuesday.

Why it matters: The jump — from 1.93% on Monday — came on the first day that public elementary classrooms reopened in the city after months of closures, but guidelines state that all public schools will have to shut if the citywide seven-day positivity rate stays above 3%.
