ADS-B not the first

In the story, FAA to expand ADS-B nationwide in the Aug. 24 issue, it says that ADS-B promises to increase situational awareness for all pilots because, for the first time, pilots will be able to see real-time displays of traffic.

Does no one else remember reading of the experiment at Atlanta wherein the approach control radar screen display was transmitted on a UHF television channel and received by a portable TV set in the aircraft?

I recall reading of this — probably in the late 1950s or early 1960s — in a magazine.

I think it worked so well that it was halted right away, possibly because the FAA could not control the quality of receiving TV sets.

I think ADS-B is NOT the first time real-time display of traffic has been available.
