APPLE TV just did this during our current holiday season and it bit them in the butt! Apple bought the rights to the Charlie Brown holiday series so those of us who enjoy these annual traditions we CUT OUT from being able to watch The Great Pumpkin and they had planned to cut us out of the TX and Christmas shows. Next thing you know, folks ganged up on Apple (as they should have) and these shows have and will appear on PBS "courtesy of Apple TV".
Same kind of thing happened a few years back with "It's a Wonderful Life" when HBO (I think) bought the rights and us common folks did not get to see the show.
There's going to be some serious shake-outs coming down the road.
