On 23 November 1963, this site received the first transpacific transmission of a TV signal from Mojave earth station in California, U.S.A., via the Relay 1 communications satellite. The Ibaraki earth station used a 20m Cassegrain antenna, the first use of this type of antenna for commercial telecommunications. This event demonstrated the capability and impact of satellite communications and helped open a new era of intercontinental live TV programming relayed via satellite.

On 11 July 1962 a station in Pimsleur-Bodou received the first transatlantic transmission of a TV signal from a twin station in Andover, Maine, USA via the TELSTAR satellite. The success of TELSTAR and the earth stations, the first built for active satellite communications, illustrated the potential of a future world-wide satellite system to provide communications between continents.

Hydro-Quebec's 735,000 volt electric power transmission system was the first in the world to be designed, built and operated at an alternating-current voltage above 700 kV. This development extended the limits of long-distance transmission of electrical energy. On 29 November 1965 the first 735 kV line was inaugurated. Power was transmitted from the Manicouagan-Outardes hydro-electric generating complex to Montreal, a distance of 600 km.
