Many other one-off experiments took place in the next few years, but none led to continuing scheduled services. Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model.

Imagine how entertaining it can be if you are the news anchor on a national television channel or you are the host of a popular radio show. The first regular television broadcasts started in 1937.

Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. The world's technological capacity to receive information through one-way broadcast networks more than quadrupled during the two decades from 1986 to 2007, from 432 exabytes of (optimally compressed) information, to 1.9 zettabytes. There is no way to predetermine how the larger population or audience will absorb the message. After the war, renewed interest in radio broadcasts grew out of experimenters’ efforts, though such broadcasts were neither officially authorized nor licensed by government agencies, as would become the practice in most countries by the late 1920s. Interior of the KDKA “radio shack,” constructed atop the Westinghouse building in Pittsburgh, Pennsylvania, October 1920.

To fully understand the multiple broadcasting systems, you must first know the definition of broadcasting and a broadcasting system. or Terrestrial Television is probably one of the most resilient broadcasting systems today.

Reginald Fessenden (right) and coworkers in their radio station at Brant Rock, Massachusetts. Nevertheless, very few people heard these early broadcasts—most people merely heard about them—in part because the only available receivers were those handmade by radio enthusiasts, the majority of them men and boys. This is known as High Definition Television, and it is one of the latest systems of broadcasting. Another early station appeared in Canada when station XWA (now CFCF) in Montreal began transmitting experimentally in September 1919 and on a regular schedule the next year. They can choose to listen, analyze, or simply ignore it.
