Is cricket the world's second-most popular sport?

An alternative test would be how many people can recognise a star player. This would give the individual sports a boost, since stars like Roger Federer and Michael Schumacher have their faces adorned on billboards around the world—although I also refuse to believe there is a single person on the subcontinent who would be unable to put a name to a picture of Sachin Tendulkar (27m Google hits, pictured above). And there are probably undiscovered Amazonian tribes that could finger David Beckham (67m).
