Final answer:
National advertisers and local stations engage in a barter syndication arrangement for mutual benefit, with local stations known as affiliates airing network programming. Barter syndication provides national reach for advertisers and free content for stations, that also sell ad time locally. Thus, the option "C" is the correct answer.
Step-by-step explanation:
Under a barter syndication arrangement, national advertisers can participate in the syndication market with the convenience of a network-type buy while local stations get free programming as well as some advertising time to sell to local or spot advertisers. This model allows for the symbiotic relationship between national networks, local stations, and advertisers. National advertisers leverage the extensive reach provided by the syndication of popular programming, while local stations benefit by gaining access to quality content without the upfront costs typically associated with it. Additionally, they can generate revenue through the sale of advertising slots during these programs.
Local stations that broadcast national network programming are called affiliates. These affiliates agree to air programming and commercials at designated times, except during emergencies when local updates may interrupt the schedule. Cable programming offers a different model, where networks reach viewers directly through the local cable systems, without the need for local affiliates, and target specific markets and demographics with their advertising.
