The satellite, in orbit near the International Date Line, had the addition of a wideband channel for television and was used to telecast the 1964 Summer Olympics in Tokyo to the United States. Although Syncom 3 is sometimes credited with the first television program to cross the Pacific Ocean, the Relay 1 satellite first broadcast television from the United States to Japan on November 22, 1963.
Turned off in 1969, Syncom 3 remains in geosynchronous orbit as of December 2012. In 40 years it has drifted 8 degrees to the west, to longitude 172.
