Final answer:
The statement that many program conventions in television came from radio is true. Radio established various programming formats and engagement with audiences that television later adopted as it became a popular household medium.
Step-by-step explanation:
Many of the program conventions on television came from radio. This statement is true. Radio programming preceded television, but both mediums have played significant roles in shaping people's lives by providing information and entertainment in the comfort of homes. This created a unique sense of immediacy and community with events such as the 9/11 attacks being experienced in real-time through these mediums. Program formats like comedies, dramas, talk shows, and game shows originated on the radio during its golden age and carried over to television as it became a household medium.
Historically, with radio news starting in the 1920s and networks like NBC and CBS emerging, these platforms introduced various program types supported by advertising. This transformed into what we know today as traditional broadcasting, and when television came along, it adopted many of these formats, thus solidifying the truth of the statement that many television conventions have their roots in radio.
