Because Fox News' The 1/2 Hour News Hour fared so well, CNN Headline News is making another go at the "news as entertainment" doctrine with Not Just Another Cable News Show, a weekend show that dives into the CNN video archives, pulls out clips of yesteryear, and asks talking heads like Rachel Sklar and Ana Marie Cox to remember them. It debuts April 5, already has Mediaweek calling it "reliably snarky," and should be off the air by summertime.
