Once upon a time, everything on radio was live.
Eventually, there was a need to put programs on when there was no staff. Timers and relays were used to switch audio and start tape machines.
Over the years, especially to fill the long overnight hours, complex automation systems were developed. Some stations were automated all day long. Some of them filled an entire room - or more.
Today, many stations use a computer.

Schafer
Perhaps the most famous of all the automation
systems. In 1956 Paul Schafer developed an automation system
using reel-to-reel machines, even for commercials - where the emulsion was
wiped clean and counted, so it could be set to the number selected by the
numbered knobs. |

Broadcast Electronics In 19xx, Broadcast Electronics was formed to manufacture the Spotmaster brand. Quite a few announcers who got their start in the 1960s remember the distinctive lever, used to engage the cartridge. |
