The NCAA College Basketball Championships on your mobile. Popularly known as March Madness, the two tournaments (one for men's teams the other for the women) each feature the top 68 mens and 65 womens US college teams in a 3 week long single elimination tournament.
March Madness is easily the most popular college sports event in the country. I think its appeal is due to the large number of teams, increasing the likelihood of your alma mater participating, and for gamblers the lure of so many chances to win or loose in a short period of time. It also helps that each successive round cuts the pool in half with the later rounds having the memorable alliterative names like "Sweet 16", "Elite 8" and "Final 4".
Follow all the action on your phone with these March Madness mobile Webapps.
