For 60 years the CBS logo has been watching you watch TV. The iconic eye logo debuted 60 years ago on Oct. 20, 1951 and has been an ever-present fixture on the network.

"From the Network to the Corporation, the CBS Eye is an enduring asset of our company and a major source of pride for all of us," Leslie Moonves, president and CEO of CBS Corporation, said in a statement. "It is a corporate logo that is known and respected all around the world, and continues to be a fitting symbol of CBS's proud history and ongoing leadership."

To celebrate the big birthday, CBS.com is replacing its homepage's current CBS Eye with the original logo and providing visitors an explanation of its significance and history.

At 8PM ET, the network will broadcast a segment showcasing the various logos throughout the years.

I'm not sure how identifiable the Nickelodeon logo is. They've used it for a while, but I don't think it's as tied into the network as, say, the CBS eye logo, though kids would probably beg to differ. But all networks update or replace their logos at some point, and now Nickelodeon is doing the same thing. They're getting rid of the splat.

One of the reasons is pretty funny: the network execs realized it looked terrible on their business cards.

So what should replace this logo?
