Watching NCAA games in person, the extended time taken for commercials really stands out and makes watching what should be a joyful experience a painful one.
It is much worse though trying to watch a game live on TV. The continued attempts to insert more and longer commercials for NCAA tourney games really detracts the fan experience and when/if viewership is down this year, this is a big reason why.
You can't keep extending commercial time in an unlimited fashion without paying a heavy price. Viewers will either leave (that happened with me) or record the games and watch them with the commercials fast forwarded.
I wish the NCAA had 1/100th of the integrity of the Masters, where the number and length of commercials are severely limited during live broadcasts. It is a shame it is run by greedy and shortsighted idiots.
