The issue with normal television is that I may not want to or be able to watch that show at 8pm. And there's no technical reason anymore that I have to. So why not give consumers a legal and profitable for the content owners option to consume shows whenever they want?
I just don't comprehend their thinking.
I suppose I could do the same thing with TV if I had a DVR.
For many other shows though, I'm reminded of an interview with Joss Whedon (I couldn't find it in a quick Google search) in which he argues against the commercial break, and I agree. For dramas and serial episodes, it really sucks to break the flow of a story for an arbitrary break. ANY break, even for just a few seconds, sucks horribly. Having to write your stories in a way where you plan out where the commercial breaks are is an art form. Making sure that the breaks are carefully planned takes skill. Networks like TBS (I think they still do it) which put arbitrary breaks in that were not intended screws this all up.
The first season of Alias made this work, in that they were able to work in the commercial break, along with old-fashioned cliff-hangers at the end of each episode, but they eventually gave that up.
I would gladly pay Hulu for commercial-less shows. What I've been doing lately, however oddball that it is, is finding shows I never watched before that are highly regarded, and watch those shows in serial form.
I've been buying the DVDs for the shows (small cost, really) and then ripping it to disk. I've recently gone through a slew of shows this way, and without commercial interruption, it's SO much easier to get into.
