Hollywood knows how this works, and they do not incorporate or IPO each individual TV show: instead they incorporate studios, that produce many different shows. Facebook is forced into this model too by reality, thus they bought Instagram, and tried to buy Snapchat. Those shows will also have a limited lifetime. Facebook will fail, because they do not recognize that they are in the entertainment business and they will cling to their one single show.
Someone needs to create a non-gaming software studio, that is tooled to make or to buy Instagrams for less than $1bn, knowing that they constantly need to retire the old shows and come up with the new ones.
