What does this means for those that have Barker TPIR episodes uploaded on YouTube?
Although in TV anything is possible to change or have altered by some contract somewhere, more than likely it's the status quo. Fremantle keeps hitting the videos for ContentID targeting, collects the Youtube ad revenue, and nothing changes.
Fremantle makes ad revenue on the vast majority of game show fan Youtube uploads of their content, including Price - and enough for the cost/benefit to skew towards keeping them up. They aren't going to kill the golden goose unless and until they absolutely have to. (They also get to see demographic and device data, which can be hugely useful)
