Television broadcasting transmits video programs to televisions. One transmitter sends. Many receivers watch. It is a one-to-many model. Broadcast TV uses VHF and UHF bands. Digital broadcasting replaced analog in most countries. It offers better picture and sound. It also frees spectrum for mobile services.

Broadcast TV began in the 1930s and 1940s. It became the dominant mass medium. Families gathered around the set. It shaped culture, politics, and news. Cable and satellite added more channels. Streaming is now replacing them all. But broadcast TV still reaches millions, especially for live events and emergencies.

Television broadcasting types

• Terrestrial: over-the-air, antennas
• Cable: coaxial, many channels

Television broadcasting is changing. The spectrum is being repurposed. Broadcasters are moving to digital and streaming. But live sports, news, and emergency alerts still rely on broadcast. The medium is old. It is not dead. It is adapting.
