How long is a college basketball game on TV?

The average game lasts about 3 hours; in fact, it's often more than this. Technically, there are four quarters of 15 minutes each. And there is a halftime of 20 minutes. OT will always be more than 3. It's a 30-minute halftime. Or it may take days in a tie breaker, so if both teams had 21 at the end of the last quarter it will become a tie breaker so the first team to get another touchdown wins but it may take days doing so.
