Re: What is the purpose of these shows?
NXT is extremely important. It's their developmental show, where their youngest and newest guys can improve their skills in the ring and on the mic, and develop gimmicks instead of throwing them in the deep end before they are ready.
SMS reaches a different demographic, in the Saturday morning kids show, it's a good investment.
Main Event brings in more money, so far it has been no more effort than Superstars to make, but with big matches that bring in good ratings from ION.
Superstars is a contractual thing.
Frankly, NXT and ME are better than RAW almost every week.
