Electric used to use them on their coaxial long lines that fed video
cross country before TV satellites were available. If you're old enough
to remember the nationwide live video feed after President Kennedy was
assassinated, the techs and engineers at ATT patched together the first
nationwide feed by connecting the different network's feeds together to
provide all network stations with live video and did the same with the
audio feeds.
