Disinformation:

Host Adam Savage of Mythbusters tells how Visa, Mastercard, and Discover had the Discovery Channel put the kibosh on an episode that would have revealed just how “trackable and hackable” the RFID chips found in many credit cards are. It’s a telling example of how corporate advertisers serve as the gatekeepers of mainstream media/entertainment.

The video with the story has Mythbusters host (and fellow Mac user!) Adam Savage explaining how their investigation was shut down by The Discovery Channel.
