The term "television network" refers to a collection of television stations that are owned and operated by one company or organization. These networks produce their own content, including news programs, sports events, movies, dramas, comedies, reality shows, and more, which they then broadcast on their affiliated TV stations across the country (or even worldwide). Some well-known television networks include ABC, NBC, CBS, Fox, The CW, PBS, and many others. These networks compete with each other for viewers and advertising dollars, and often produce popular shows that become cultural phenomena.
