Stretching the definition a little, satellite TV had been a thing for years by then. Neiman Marcus was selling satellite dishes in 1979.

    There was a satellite ISP for a time. The satellite box had a modem in it and your outbound traffic went out over the modem and the inbound traffic came down to the dish.

    One-way communication is still communication. Broadcast TV is still used today.
