At CBS, they're turning back the clock a different way. Instead of reviving a 1990s show like NBC ("Will & Grace") and ABC ("Roseanne"), CBS will launch a "Young Sheldon" fall sitcom about the childhood of "Big Bang Theory" main character Dr. Sheldon Cooper.

Is this a good idea? CBS plans a "Big Bang Theory" spin-off for the fall TV season called "Young Sheldon," about Sheldon Cooper at age 9.

"Big Bang" creator Chuck Lorre and producer Steve Molaro are creating the sitcom starring Iain Armitage (HBO's "Big Little Lies") as little Sheldon living in east Texas with his family and "going to high school," CBS says.
