This Hollywood Reporter story takes the tack that DVR use, while spreading, isn't having that much of an impact yet:

DVRs are now in 36% of all U.S. homes, four times more than the penetration of just four years ago, according to a study from Leichtman Research Group. But even with the deployment of all those time-shifting devices, more than 90% of TV viewing in the country remains the traditional, live-linear type.

I'm not so sure though. I know plenty of football fans who start watching their favorite teams play 15 minutes after the game starts - so that they can watch the entire game without ads. We do the same thing with most shows we watch "live", and I suspect that a fair number of the respondents do the same thing. A few things are impacting the whole "ad supported broadcast model:

• DVRs
• Online watching, like Hulu
• Online buying, like iTunes
• The sheer number of things to watch, which atomizes the audience into lots of smaller niches

Online buying alone is an under-noticed thing, I think. My daughter watches a lot of stuff that way, as do many of her friends. I think a survey of how teens are consuming media would get very different results than one looking at the overall space, like this one did...
