Radio Lollipop was founded in 1978 at Queen Mary's Children's Hospital located in in Surrey, UK. The small hospital housed some 460 children. The station made its first broadcast on 5 May 1979, when the very first Radio Lollipop went on-air.
If you were curious, there is no similar domestic service in the United States. The closest service we have is Companion Radio, a service for Convalescent Hospitals and Retirement Homes in New York and New Jersey. More here. It's a totally worthy service, but it targets the elderly, not children. Radio Lollipop has opened two stations in the US: Nicklaus Children's Hospital in Miami, FL and Texas Children's Hospital, Houston TX.
By comparison they have ten affiliates in the UK, eleven in Australia, and 6 more in New Zealand. According to Lollipop central (I made that phrase up) "...each Radio Lollipop station has its own team of Volunteers who run the radio station, involve children in play activities and use the sounds of radio to stimulate the children´s imaginations."
