Answer:
Spot advertising
Step-by-step explanation:
Spot advertising refers to commercials on local television stations for which the advertisers negotiate directly with the individual stations.
Spot TV advertising refers to the common advertising approach of buying 30 or 60 second ad placements on a particular station.
Before an advertiser buys spots, it must produce one or more commercials. Then, the company or its ad agency buys a package of spots through a network or station.
