There's been some interesting darting documentaries on recently too. Popularity is soaring, I was staggered to see that there's now a Sky Darts channel dedicated to it!
If 'sport' wasn't such a large umbrella I would probably call darts a competitive skill rather than a sport, but who cares, it can be just as entertaining and competitive as a five set Wimbledon final or a marathon even if it doesn't require the same level of fitness or other attributes.
