Broadcasting networks are organizations that distribute audio and video content to a wide audience through various platforms, such as television and radio. They create and acquire programs, which are then transmitted to local stations or directly to viewers. Major broadcasting networks include ABC, NBC, and CBS in the United States. These networks operate on a national or regional level, providing a mix of news, entertainment, and educational programming. They often rely on advertising revenue and subscription fees to fund their operations. Additionally, many networks have expanded into digital platforms, allowing viewers to access content online through streaming services.
