From the Brilliant Ideas That Will Never Work file:

With most television services, you can pay a lot of money and get every
channel ever, or you can pay less money and get fewer channels.

For those customers who chose to pay less money and get fewer channels, they
should give them random daily previews of other channels. Customers get,
say, one free hour per week of every channel they don't subscribe to, with
the exception of pay per view and any channels they choose to block. The fun
part is that the free hour is totally randomized, generated by a computer
program. You never know when a channel is going to be available, or which
of the channels are available at a given time. So you're flipping channels
(aside: they need a system where you flip channels and automatically hit
every channel you're currently getting, which some TVs have and some don't)
and suddenly there's this channel you don't pay for! Is it interesting? Do
you want more? Should you pay for this, or try your luck again next week?
