"I doubt it would be wise for CBS to attempt a programming strategy last tried nearly 60 years ago."
By that logic, NBC ought to dump the Tonight Show with Jay Leno, and CBS should cancel The Late Show with David Letterman, because they're all variations on a theme first created by Steve Allen and Pat Weaver back in 1953 on WNBT in New York.
In television, like everything else, it's not necessarily the strategy itself that needs to be all-new--it's the way the strategy is executed. A new iteration of a successful mix of information and light entertainment from the past would be enough of a change of pace in the 7-9 AM daypart to attract sampling--and if it's well done with appealing personalities to present it, it could become a very successful morning show that holds and builds an audience. CBS has little to lose at this point by breaking away from the news parade.
Agreed. CBS is offering a product that is much different than Today and GMA. I like it. Time will tell if they make any inroads.
