My first idea was to send ascii messages through the unused space already being sent over the wireless cell towers so people could communicate in another way and you could charge them a somewhat nominal fee but rack up millions in profit.
THEN after that one fell flat, my next idea was to make some horrible TV reality show where we put homosexuals, women and generally effeminate metrosexual men that can sing well but without any style and have them fight for popularity. THEN we'd have everyone watching send text messages to vote for them, thus racking up more millions.
Unfortunately these will never see the light of day.
