Commercial television refers to television programming that is funded primarily through advertising revenue. This means that networks and channels create content to attract viewers, who are then exposed to advertisements during commercial breaks. The goal is to generate profit by selling advertising space to businesses looking to promote their products or services. In many countries, commercial television operates alongside public broadcasting services, which are funded by government support or viewer subscriptions. Popular examples of commercial television networks include NBC, CBS, and ABC in the United States. These networks often produce a variety of shows, including dramas, comedies, and reality programs, to appeal to a broad audience.
