Because they need one.
Even as the oil continues to gush from the sea floor, and the networks shuttle their anchors to points along the Gulf coast, NBC Nightly News, ABC World News and the CBS Evening News continue to lose viewers. All three broadcasts were down in Q2 2010 compared to the same period last year.
In numbers released today, NBC Nightly News with Brian Williams lost -440,000 viewers (-140k in A25-54 demo) compared to Q2 2009. ABC's World News with Diane Sawyer lost -260,000 viewers (-80k demo) (Charlie Gibson was anchor in 2009). The CBS Evening News with Katie Couric lost the most, based on a percentage, losing -340,000 viewers (30k demo) compared to Q2 2009. ABC and CBS were also down when Q2 2008 is compared to Q2 2009.
Many reasons for this. With the internet and news/talk radio I know everything before 6:30pm. Include the fact that these guys have their heads so far up Obama's orifice that they need a flashlight and you can see why a guy who doesn't even have cable can live without the 6:30pm nightly newscast.
Here is my plan to make CBS news the #1 rated telecast. Fire the perky one, (who is really getting hammered) and hire former FOX newsguy Brit Hume as your nightly anchor. It would be a true alternative, like showing figure skating or a chick flick when the other network is showing the Super Bowl. I haven't watched network news in nearly 20 years and I would tune in.
But that will never happen, and everyone reading this knows why.
