Even if you've never watched college basketball before you can still get in on the post-season action. Here's a guide to what's become more than just a 65 team show.

NCAA: 65-team field chosen by an NCAA committee including athletic directors and conference commissioners (including Jon LeCrone of the Horizon League) with 31 conference champions and 34 at-large teams. Begins with play-in game March 18 at Dayton. Rest of tournament begins March 20-21 at regional sites. Championship game at San Antonio, April 7.

NIT: 32-team field now owned and operated by the NCAA. All regular-season conference champions who do not make the NCAA field are automatic qualifiers. The rest will be chosen by a selection committee of seven, including chairman C.M. Newton (former coach and former athletics director at Kentucky), Gene Keady (former Purdue coach) and Don DeVoe (former OSU player and coach at Tennessee, etc.). Home sites until the final four, then moves to New York. First games played March 18. Championship game at New York's Madison Square Garden April 3.

CBI: New entry into the post-season this year. The Gazelle Group of Princeton, N.J., which has run several early-season NCAA tournaments, will select (with its own staff) 16 teams playing all games at home sites beginning March 18. The final two teams will play a best-of-3 series, March 31, April 2 and April 4 if necessary.

TV: NCAA will be broadcast by CBS (except for play-in game, by ESPN) and will have a 6 p.m. show tonight announcing the brackets. NIT will be broadcast by various ESPN platforms with a selection show on ESPN2 tonight at 9. CBI will be broadcast by various Fox College Sports networks with no broadcast show tonight.
