Broadcast
journalism is the field of news and journals which are
"broadcast", that is, published by electrical methods,
instead of the older methods, such as printed newspapers
and posters. Broadcast methods include radio (via air,
cable, and Internet), television (via air, cable, and
Internet), and, especially recently, the Internet
generally. Such media disperse pictures (static and
moving), visual text, and/or sounds. [Wikipedia]
