From The Hoop Doctors:

Word is starting to spread this week that the NBA this season will be allowing teams to accept advertising offers to place advertisements on their practice jersey’s. There has been no information yet on the regulations that would govern where and how many ads an NBA team would be allowed to put on their practice jersey’s. It seems the league wants to use the practice jersey’s as a beta program for gauging their overall comfort level with allowing ads on the game jersey’s.

How long before video games permeate this ad space, a la FIFA
