Final answer:
The WB, by supplying programming to affiliated independent television stations, serves as a television network. Networks distribute programming to local affiliates, shaping viewer's content while competing for ratings and ad revenue.
Step-by-step explanation:
The WB, known for providing programming and other services to its group of affiliated independent television stations, is an example of a television network. By definition, television networks like CBS, NBC, or The WB itself, distribute programs they purchase the rights for to their local affiliate stations, which then broadcast those programs to local viewers. These local stations, or affiliates, typically have agreements with the networks to give priority to their programming, including news and other national content.
Over time, television has been shaped significantly by the presence of these networks, which have competed for ratings and advertising dollars. Major networks, including the conglomerates behind them, own a vast array of television stations and command a large portion of the programming seen by viewers. While the number of major conglomerates has lessened, they still continue to exert influence over the programming through the various channels and networks they own.
