Pretty much all north American sports are becoming unwatchable anymore because of TV and specifically the ever increasing and lengthening commercial breaks.
Hockey was not meant to have media timeouts, now they're even present in the USHL and NCAA. But they aren't present in overtime, which is why a full 20 minute OT can be played in about 30 minutes instead of the 45 minutes that is standard during regulation.
Baseball has 17 natural commercial breaks, but they've doubled or even trebled in length in the last couple decades, even for pitching changes.
College football used to be a 2.5 hour event. These days a non-OT game can take almost 4 hours.
College basketball's media timeouts aren't horrible unless it's an ESPN game, because they go from 90 seconds to 150 seconds in that case.
I really wonder if live audiences will ever revolt as sports cater more and more to the television audience to the detriment of the live experience.
