They make no bones about it. Federer is who the majority want to see, so they show him at every opportunity. The BBC Wimbledon coverage isn’t and never has been for tennis fans, it’s for the British public who happen to watch a bit of tennis for two weeks a year.
And personally I’m not that peeved about that. It’s no excuse for continuing to employ goobers like Inverdale and Lloyd, but it does serve the public, and the fact that we can now watch most courts online means I’ve spent quite a lot of the last week and a half watching my laptop, while the telly has football on mute.
