Part of the BBC F1 summer break page has a quiz that asks you to name all 33 F1 champions. Having completed it I of course then grumbled about it to the BBC via their contact pages. Because the World Championship was for Formula 2 cars in 1952 and 1953. And technically it wasn't the Formula One World Championship anyway before 1981 - it was the World Championship of Drivers (with the International Cup for Constructors alongside).
