He has written several books, including The New York Times bestsellers America Alone, After America, and Broadway Babies Say Goodnight. In the US he has guest-hosted the nationally syndicated Rush Limbaugh Show, as well as Tucker Carlson Tonight on Fox News, on which he regularly appeared as a guest and fill-in host. In 2021, Steyn began hosting his own show on British news channel GB News. He left GB News in early February 2023, saying that the channel wanted him to pay fines issued by the UK media regulator Ofcom, which was investigating complaints of COVID-19 vaccination scepticism aired on The Mark Steyn Show. He has since moved his show to his own website.
