It's now harder to get a ticket for a London NFL game than a Beyoncé concert - so where next for American football in the UK?

A decade ago it seemed unthinkable that the British public would be scrambling to watch the Tennessee Titans in the same way they do Justin Timberlake. Sky Sports now airs as many NFL games per week as it does Premier League. You regularly see American football stories take up prime positions on the BBC Sport website, and I challenge you to spend more than 20 minutes walking around a big city without seeing someone in a Cowboys jacket, a Giants cap, or a Patriots beanie.
