Winning NBA rights was only the start for NBCUniversal . Now the company needs to get viewers to watch dozens of games slated for broadcast across NBC and Peacock. At the company’s 30 Rockefeller Plaza headquarters next week, NBC will open a custom LED basketball half-court, with 30 pieces of team-inspired basketball artwork, using the so-called “30 Rocks at 30 Rock” display to generate interest in the company’s new NBA schedule.
