How has television news coverage of Covid-19 vaccines compared with online coverage? The timeline below shows the percentage of airtime across CNN, MSNBC and Fox News mentioning vaccination since the start of 2020 using data from the Internet Archive's Television News Archive, showing how mentions soared after Pfizer's early November announcement, but that since the middle of December, mentions have been trending down. Noteably, since the inauguration CNN and MSNBC have refocused on vaccination, while Fox News has not. The large shifts in attention reflect the fact that television news has a fixed amount of daily airtime, meaning that as breaking stories emerge they displace other stories like vaccination.
