In some situations, not everyone watches the same ads. If you are watching a local rebroadcaster, the ads can be (and in my experience, are) replaced with more relevant ads to your town/city. "A television re-broadcaster may sell local or regional advertising for broadcast only on the local transmitter. Rarely, they may air limited programming distinct from their parent station. Some "semi-satellites" broadcast local newscasts or separate news segments in part of a newscast."[0] [0] https://en.wikipedia.org/wiki/Broadcast_relay_station https://en.wikipedia.org/wiki/Broadcast_relay_station
