I'm not really debating the popularity of football. Here in the UK it's popular - I'd guess that about 30% to 50% of adults watch it regularly (in a pub or going to a game), with maybe 1/4 of those being interested enough to pay for a TV service to watch it at home. It definitely isn't even close to "all middle to upper class families" as thegenius2000 suggested might be the case in Kenya though.
An interesting related statistic: Almost twice as many people go to the theatre in London as go to all the major Premiership football games[1]. I doubt many people would guess that if they were asked.
