From what I've seen, ad viewing rates in America for TiVO et al are much lower than that. Seems like that's a change from what used to be reported, so maybe ad viewing rates go down as people become used to DVRs. Anyway, the advertisers refuse to pay more for DVR viewing and if people were watching ads, the networks would have a better argument for making them pay up. But that's not happening.There have been studies, I'm guessing only relevant to the UK, which suggest even with a DVR views still watch around 30% of the adverts,
I'm not entirely certain how they reached that number, I mean I know personally I fast forward nearly 100% of the time, and the only time I watch live is when it's on HD because I don't have a HD DVR yet. But if an ad catches my eye while I'm fast forwarding I will rewind and watch it, and I know I'm not the only one, I know at least 2 others who do too.
Also, they say people look for, and stop when I see the sponsor bumper, so perhaps they're counting those too.
I know there have been a couple of attempts to get round advert skipping, by having ads that are just a block of text on the screen for 30 seconds, so even if you're fast forwarding you can read the block of text.
I know it's not the same over there, but over here there have been subscription free DVRs for some time now. They don't offer the same service as Tivo and the like but they are better than VCRs, offering series/daily/weekly record, accurate recording capabilities and dual channel recording. Perhaps they'll happen over there once Digital Switch over is complete?
