More than 21 million watched the Saturday morning announcement that Joe Biden has won the presidency

The New York Times

The 21 million represents viewership on the three biggest cable news networks (MSNBC, CNN and Fox News) and the Big Three broadcast networks (CBS, ABC and NBC), representing an unusually high viewership for a Saturday morning. "On CNN, viewership jumped 36 percent at 11:30, six minutes after the network became the first to project the Biden win," reports The New York Times' John Koblin. "The MSNBC audience jumped 29 percent at 11:30. (NBC News had made its call at 11:25.) On Fox News, which made the call at 11:40, there was a 38 percent jump. The broadcast networks broke into 'special report' mode and also saw huge spikes, according to Nielsen...CNN had, by far, the most viewers of any network, averaging around seven million between noon and 2 p.m. Eastern time. MSNBC, the home network for many liberal viewers during the Trump years, had an average of roughly 4.5 million. Fox News, which usually has a commanding lead in viewership, had about three million. Fox News viewers also began to tune out a little more quickly than viewers of the other cable networks, not long after being greeted to gleaming graphics that Mr. Biden was now president-elect. Viewers started to leave Fox News around noon, about 20 minutes after the network made its call, according to data from Nielsen."
