Stop Set
A cluster of commercials aired together as a single break in programming.
A stop set is a block of back-to-back commercials. Grouping spots into a few sets per hour — rather than scattering them — keeps longer stretches of music or content uninterrupted, which helps hold the audience.
How many stop sets an hour has, and how long each runs, is a programming decision that trades ad load against listener tune-out.
