Sometimes they are the shows you watch--as in, you may be watching a large advertisement with several smaller advertisements inserted into it.

Example: the Disneyland 60th Anniversary TV Special. Disney/ABC is particularly fond of advertising cross-medium Disney properties/investments on Disney-controlled television and radio broadcasts. For instance, Radio Disney definitely plays a disproportionately high number of DMG (Walt Disney Records + Hollywood Records/DMG Nashville) recordings.

My spouse was watching it. I saw 30 seconds of it and said, "this is a long format ad for Disney parks," before tuning it out.

The long-format ads are rather common on the local news broadcasts. Some stations show more than others.
