Since retiring from competitive track, Johnson currently works as a television commentator, often for the BBC in the United Kingdom, where he has also written columns for the "Daily Telegraph" and "The Times" newspapers. Johnson was part of the BBC's presenting team at the 2012 Olympic Games in London, and fulfilled the same role at the 2016 Olympics in Rio de Janeiro. He was in the BBC commentary booth for the men's 400 metres final in Rio de Janeiro to see his world record broken by Wayde van Niekerk, saying about van Niekerk's performance, "Oh my God! From lane eight, a world record. He took it out so quick. I have never seen anything from 200 to 400 like that. That was a massacre from Wayde van Niekerk. He just put those guys away."
