MLB will put out a contract for bid. This contract may be for hats, bats, TV rights, etc. Companies that would like to do business with MLB bid on the contract. MLB selects the bid that will be the best for them (almost always the highest bid) and awards that company the rights, called licensing agreements, to produce the hats or bats with the MLB logo or team logo.

In MLB and NCAA, at least, all team caps must have an official team logo on them. Most wear their team letter(s), but logo's can be used, like the redsox using the "2 redsocks" logo on their caps this year.
