Transpacific cable

In 1903, the first cable across the Pacific Ocean between Hawaii, Midway, Guam and Manila was completed and spliced at Manila, Philippine Islands. After testing, the first official message was sent the next day. The first section of the cable across the Pacific Ocean between San Francisco and Hawaii had already been established at the beginning of the same year, with its first official message sent on 1 Jan 1903. That technological event ended Hawaii's isolation by connecting it to the mainland U.S. and the rest of the world. The cable was a mainstay of communications into the early 1950s when newer technology rendered it obsolete. (The 1902 all-British telegraph line from Canada to Australia and New Zealand was the first line to cross the Pacific Ocean.)
