Reports that the big three networks are considering revamping Friday nights into an all-repeat night have media buyers wringing their hands. If that were to happen, one person says, buyers would have to look hard at buying time on cable, where it's still easy to find original programming on that night. The problem is that if the networks are writing off Friday night as a night no one watches TV then they're making the same assumption about the ads which decreases their value. After all, who's going to buy a ton of ad time on a night when even the programmers are convinced no one is watching. That kind of thinking is currently in place on Saturday nights, which is why you see ten year old movies and such airing on that night. What's significant is that this is now two out of seven nights where networks are throwing in the towel on viewers.
