Davenetics points at a new study that supports something I've been thinking about for a while now. This report is showing results that while PVR owners are fast-forwarding through many commercials, they're at least watching them, instead of changing channels and avoiding them altogether, as non-PVR owners often do.
Personally, I find myself watching at least one commercial per half hour of recorded content simply because it looked interesting during fast-forward. The popular industry folklore is that TiVo is killing the 30-second advertisement market, when my personal habits and this study contradict that. [thanks Dave]
