TiVo, Comcast to distribute updated unwatched ads

Here’s another item for the list of silly ideas to make TiVo advertising-friendly: it and Comcast, which announced a partnership last month, are working on a system to update the commercials in already-recorded TiVo programming. Is this so people who are catching up on already-recorded shows can now fast-forward through newer commercials? The two companies will also try to make the inserted ads more relevant to those viewing them, which sounds a bit more to the point.
