Etymology

Origin of simulcast

An Americanism dating back to 1945–50; simul(taneous) + (broad)cast

Explanation

When a program is shown on two TV channels at the same time, or simultaneously on TV and radio, that's a simulcast. Another kind of simulcast is a live broadcast. You can call a station's broadcast of the Superbowl or the Academy Awards a simulcast, although this is a newer way to use this word. It was coined in the 1940s, during the early days of television, from a portmanteau (or blend) of simultaneous and broadcast, specifically describing shows broadcast on radio and TV at the same time. If a concert is aired on two radio stations at once, that's also a simulcast.
