According to reports on MobileRead, this commercial was aired during a football game Wednesday night.
I first found this video posted with voice over on techRCcrp's Youtube account. I'm not sure who that is, but they're the ones doing the voice over. But I'm going to instead show you the original video which was posted on another Youtube account:

This video looks like it might show a few different Kindle Fires, and some are claiming they see a larger device with an attached keyboard. I think that's a laptop, not a Kindle Fire.
