Step-by-step explanation:
The buying period for television advertising time that runs throughout the entire television season is known as the up-front market. During the up-front market, advertisers can buy television advertising time before the television season begins. This allows them to secure premium advertising spots and often at a better price than if they were to buy advertising time later on, which would then fall into the scatter market. The up-front market is critical for networks since it generates a significant portion of their advertising revenue.
The local station that broadcasts national network programming is called an affiliate. These affiliates are crucial in the distribution of network content across various regions, ensuring that national advertising can reach consumers effectively. With the advent of cable and satellite TV, there have been shifts in how television advertising is handled, with more focus on targeted advertising due to the diverse range of channels available to specific market demographics.
