Answer:
Barter syndication
Step-by-step explanation:
Barter syndication is defined as a contract that exists between broadcasters like television networks, independent networks, and television syndicators. The item that is being battered is advertisement time within programs being aired.
It determines how much advertising time will be available and who will sell that time.
In this scenario advertising time is shared among various parties. The ads for Wheel of Fortune, a game show, are pre-sold to national advertisers. The rest of the advertisements for Wheel of Fortune are offered to local stations either for free or for a reduced rate.
