Zuckerberg: How Facebook is now better prepared to fight election interference

  • Why it matters: After initially denying Facebook's role in the 2016 U.S. presidential election, Facebook's CEO outlined on Wednesday night how the company has learned from its mistakes, adding it's already stopped meddling attempts in a number of elections.

Google's search engine for China: Seven employees quit; Google built a prototype

  • Why it matters: The departures follow the controversial revelation of Google’s work on Project Dragonfly, a censored search engine that would let it serve China again. The former employees cite a lack of transparency from the company as the reason for leaving. Meanwhile, Google has reportedly built a prototype that links a user's searches to their phone number, which could make them a target of the government.

Walmart relaunches Jet with three-hour deliveries

  • Why it matters: Walmart continues to battle rival Amazon, this time with a new version of Jet.com, which it bought in 2016. The new Jet.com is aimed at shoppers in large urban cities, letting them order via voice commands with Siri and offering three-hour delivery. Walmart also announced this week its acquisition of Cornershop, an on-demand grocery delivery service in Mexico and Chile.

Uber gets a new logo

  • Why it matters: The rebranding, which includes new colors, typeface and app layout, is to better match the company's expanding transportation options, it says. Uber is also still working to redeem its public image.

Google’s location privacy practices are under investigation in Arizona

  • Why it matters: Google mobile services reportedly continue to track users when they think they've turned location tracking off, causing new privacy concerns about the company.

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%.
