Radio paging service

science · 15 October 1950 · 75 years ago

In 1950, the first American radio paging service, Aircall of New York City, sent the first page to a doctor who was on a golf course 25 miles away. Subscribers carried a six-ounce pocket radio receiver and could hear their call numbers repeated in numerical sequence on the air at least once per minute within a 30-mile radius.
