Commercials during hockey game

ok i think the worst place to put your commercial is between periods of an NHL game. ok its 20 min of hockey then 15 min of straight commercial and everyone knows it! so they change he channel for 15 min. then turn back when its back on? see normal channels you either bare it out and watch a billion worthless commercials or you change the channel and come back every once and a while... but everyone knows once a period is over its 15 min of commercial?! so why watch?! but thats just me... im sure some people watch every stinkin commercial....ps commercials are getting out of control!
