I came across this site when looking how to watch Glee live online http://www.ivi.tv/guide/details/Glee I didn't want to wait until after it has aired, as that is usually days after my friends like to chat about it. Well we actually chat about it WHILE it's airing, so I hunted. I came across IVI, registered, paid, downloaded an app, and double clicked it.
Holy sh*t, live television, from New York, L. A., and a few other cities, I flipped channels up and down, and saw ABC, NBC, CBS, The CW, and whammo Fox, where Glee lives, I watched the entire episode, IM'd my friends, who all downloaded the app, and we all are never turning on our parents' televisions again!
This is the coolest thing ever, watching prime time tv during prime time, all from my white macbook while commenting on the show via Facebook and IM.
LOVE IT!
