Radio AC was first established in 2153, a few years after the Five Families cleared out the remaining mirelurk threats still in city, solidified their control of the settlement, and began rebuilding it. Initially, the station aired propaganda broadcasting how safe the city was and how prosperous those living in the city were. As wastelanders began immigrating to and settling in the city, the Five Families found it necessary to change the format of their radio tower. In addition to transmitting broadcasts designed to attract settlers, Radio AC would also begin playing music, news, and other messages for the growing population of the city.
