We are talking about corporate Strategy here. CORPORATE.
There are two things that could happen.
1. The Evil execs make mucho money from Reality TV. Then when it no longer becomes profitable they steal it all and run off ripping off a bunch of retired Pensioners for good measure
2. They take the profits they made from whoring to the lowest common denominator and restructure the network to a new flavour of the month, and continue to do this until TV becomes obsolete.
Knowing how evil fox is I would say option 1 is the most likely. However When you think about it option 2 makes a lot more sense. So I fear that will be the Ultimate outcome.
Fox Will live!!
