The impact of DVRs on TV ads

How many people record their favorite shows so they can watch them without the commercials?   Quite a few.   How many people use Netflix to see older episodes of their favorite shows without commercials?  Quite a number.   And now they are talking about giving you a DVR that eliminates commercials.

There are a couple of categories of programming that are less resistant to this.  #1 News shows.  News is current — you want to watch it right away.   #2 Sports.  Sports is also current — once you know the score, who cares.
