On tonight at 10pm on SBS channel 31, a documentary on cartoons, with episode 2 (After these Messages) noting Transformers in the description.

The episode is about consumerism (cartoons selling stuff), so it could be talking about cartoons like Transformers that were just 20 minute commercials... or maybe the merchandise that was created to cash in on cartoons.
