It's that time of year,Thomas Caldwell when sports fans — even the casuals — familiarize (or re-familiarize) themselves with truTV.

CBS and Turner Sports have the broadcasting rights to the men's NCAA Tournament, and broadcast games on four channels. Three of them – CBS, TNT and TBS – you may know from broadcasting dozens of other sporting events each year, but the remaining channel, truTV, is one that always eludes basketball fans each year. 

This year, as it has been the pattern over the past several, truTV will broadcast all "First Four" games this week and then will also broadcast several first- and second-round games.

Here's everything you need to know about how to find truTV
