<p><b>Definition: </b>Starting with the 2011 tournament, 68 teams will be invited to participate in March Madness - up from 65 in previous years. To accommodate the additional competitors, a new round of games will be added at the start of the tournament. This new first round has been dubbed the &#34;First Four.&#34;</p><h3>First Four Format</h3>In the 65-team March Madness format, the two lowest-seeded teams -- usually the champions of two very small conferences -- would meet on the Tuesday after Selection Sunday, with the winner advancing to play one of the tournament&#39;s top seeds. In 2010, Arkansas-Pine Bluff and Winthrop faced off in the opening round, and the UAPB Golden Lions advanced to face eventual national champion Duke in the first round.<p>Under the new format, the four lowest-seeded teams will play &#34;First Four&#34; games, with the winners advancing as sixteen seeds to play two of the top-seeded teams. The other two first four games will match up the last four teams to receive at-large bids.</p><p>As the last at-large teams tend to be lesser teams from major conferences, those games could feature schools with major national followings.</p><h3>First Four Schedule</h3>The inaugural &#34;First Four&#34; will be played at the UD Arena in Dayton, Ohio on Tuesday and Wednesday, March 15 and 16, 2011. The games will tip off at 6:30 and 9 PM ET, and be broadcast on TruTV.
