ARN was headquartered in Little Rock, Arkansas operating from its flagship station KARN-FM and ended its existence under the ownership of Cumulus Media.
Known for his velvet-like voice, he also did a weekend program on the Network for many years called Uncle Bob's Stories from the Bible.
The network later expanded to include the AP&L (Arkansas Power and Light, later Entergy) Live Better Electrically Hour, a program of music played in the late morning and broadcast over KARK-FM's 100 kW signal.
KARK was distributed by KARK-FM or by relays through other FM stations (KNBY-FM in Newport to KRLW-Walnut Ridge as an example).
ARN's growth came in the early 1980s, when distribution moved to satellite, although the number of affiliates had been growing into the 1970s.
