Robert Osborne, Chuck Berry, and Chuck Barris die

I've recently learned that Turner Classic Movies host Robert Osborne had died of kidney failure, Chuck Berry had died of cardiac arrest, and game show creator Chuck Barris had died of natural causes.

Bob died on the 6th at 84 years old, Chuck Berry died 12 days later (on the 18th) at 90 years old, and Chuck Barris died three days after that (on the 21st) at 87 years old.

I remember seeing Bob on a few TCM interstitials, and I haven't remembered Chuck Berry, but I know that Chuck Barris created game shows like The Dating Game and The Newlywed Game among others.
