I don't have cable and digital TV rarely makes it down into my house, so I have to watch online. I often go to the website of the TV company to get the shows I like. NBC, CBS and PBS usually have their shows a day later. I recently started watching "Men of a Certain Age" on TNT.TV and was delighted to see that they just put ALL of the episodes online! That should keep me laughing for a while.
The only shows that I watch on the computer (and rarely i do that) are The Daily Show, The Colbert Report (on the Canadian Comedy Network), Hell's Kitchen, Master Chef (on Youtube) and The Graham Norton Show (on Youtube...never watch it on BBC Canada [anyway i think its only old show...never saw new shows when i pass through there when its on] because there its censored). I also was able to see a few shows with Gordon Ramsay that never aired here and also shows that aired but learned about them after it started. The other shows I watched and are watching I'm not able to watch on the internet so I make sure to watch them even when I am tired and want to go to sleep. I follow the Dallas Stars so I often have to watch a show on replay or on the western time (rare times when i can see a show on the American channel so i prefer that time zone anyway for that reason...Fringe always worked like that).
