If the NFL playoff games weren't filled with enough unexpected action to keep you awake this past Sunday, something else was -- a screaming clown.

Walmart aired a new commercial during the games this weekend meant to promote its low prices on party supplies.

Good timing, considering millions of Americans are getting ready to host parties for the Feb. 7 Super Bowl game.

The Walmart ad, which features a misplaced unicorn and a screaming clown, has taken on a life of its own online. It now ranks as the No. 5 on the Viral Video Chart. It's quite a change from a few years ago, when the most action in a Walmart ad was an animated yellow happy face racing around its stores, slashing prices.

Look out nerdy-cool Apple guy, the empire is striking back. And it’s got Eva Longoria Parker, Tony Parker, Pharrell Williams and Deepak Chopra on its side.

Microsoft is launching (another) new commercial campaign Thursday night. It takes aim at Apple’s “Mac vs. PC” campaign that has portrayed personal computers running Windows as clunky and uncool.

The commercial starts with a real-life Windows engineer who looks eerily similar to John Hodgman (the comedian who plays the role of “PC” in Apple’s commercials), saying “I’m a PC and I’ve been made into a stereotype.” After that is a montage of celebs and normal folk, saying “I’m a PC.”   Microsoft co-founder Bill Gates, along with the aforementioned celebrities, makes an appearance in the ad.
