Digital Video Records (DVRs) like Tivo have clearly impacted the viewing habits of millions of TV watchers. Viewers can now view their shows whenever they want. This has thrown the traditional TV advertising business on its head. For example, I can't remember the last time I watched a show live and I can't remember the last time I watched a commercial (except for eBay's IT campaign).

However, my viewing habits may need to change as I've noticed it is increasingly difficult to actually not find out the details of an episode before I watch on my Tivo. Whether by hearing the details on the radio, catching a peak of a story on the Internet or hearing it from a friend or colleague, I seem to know all the big juicy details before I view my recorded programs. It has gotten so bad that I'm actually considering watching live TV again (or atleast avoiding the radio, Internet and human contact). This makes you wonder if the networks are making all this information easily available to change viewing habits. I wouldn't put it past them. The networks have never been good at adapting.
