Television
While televisions were available in the 1930s, the popularity only increased drastically in homes during the late 1940s to the 1950s.
In my opinion, television is the most popular mass medium in Morocco, the internet comes second and then,the print media in the third square :)
There were no TV shows in 1917; television did not come into use until the 1940's (and it was used by very few people until the 1950's, when it became popular). There also were no radio shows in 1917. The only mass communication medium in 1917 was the newspaper.
I think what you are trying to say is that film is an "example of" mass communication. In other words, film (or movies) is one of the mass media. A mass medium sends out a message to a large and often distant and anonymous audience; we don't know who is listening to our radio show or who is reading our book, and the audience could come from anywhere. (And by the way, "medium" is singular-- radio is a mass medium. Radio and television are mass "media," plural.) Examples of mass media are radio, TV, movies, books, magazines, the internet, and newspapers. All of these are in the category known as "mass communication."
It was once newspapers but in our modern world it is now Television
The mass of a TV can vary depending on the size and model. On average, a small to medium-sized TV can weigh anywhere from 5-20 kilograms, which is equivalent to 5000-20000 grams.
Television was considered the true mass medium as it reached a large and diverse audience, shaping public opinion and influencing culture on a wide scale. It had the power to transmit information, entertainment, and advertising to millions of viewers simultaneously.
The first mass medium was the printing press, invented by Johannes Gutenberg in the 15th century. This invention revolutionized the way information could be produced and distributed to a wider audience, marking the beginning of mass communication.
The golden age of radio was the 1940's, which was before television took over as the most important mass communication medium.
"Broadcast medium" refers to a method of transmitting information, such as radio or television, to a wide audience simultaneously. It allows for mass communication of messages to reach a large number of people at the same time.
By definition, mass communication is a message created by a person or a group of people sent through a transmitting device (a medium) to a large audience or market. It is the delivery of messages to general public by utilizing mass media such as national press, radio, and television.
