Why did CNN air a special about the band Chicago?

I admit that I taped it, and I'm a fan of the band, but I was wondering why in the world CNN decided to air a special about them on New Years Day. Was there something new that happened to the band? Not really. They were inducted into the Hall of Fame...nearly a year ago. Sure, they are about to go on a tour...but they do that every year. Not exactly newsworthy. Are they suddenly popular again? Nope.

So what's the deal?

The Washington Post asked the same question, and their media writer Paul Farhi delved into it.
