Geostationary satellite (Syncom)
A satellite hanging still over the Pacific broadcasts the Tokyo Olympics live.
Hughes' Syncom 2 of 1963 was the first geosynchronous satellite, and Syncom 3 in 1964 became geostationary, realising Arthur C. Clarke's 1945 proposal. Fixed-position satellites let dishes point once and stay put, the basis of satellite TV and global telephony.
