1988 in radio

Events

• February - Longtime St. Louis rocker KWK 106.5, tired of playing second-fiddle to KSHE 94.7, flips to CHR/Top-40 as WKBQ "Q-106.5" to try its luck going after consistently top-3 rated KHTR 103.3. Although the station skews younger, it shaves off enough of KHTR's younger audience to drop it to the middle-of-the-pack and forces a format change later in the year.
• August 13 – Los Angeles radio personality Shadoe Stevens takes over as host of "American Top 40." He replaces Casey Kasem, who had hosted since the show's debut in 1970. Stevens will remain with the program until the end of its original run in January 1995.
• September – KMGK in Minneapolis, Minnesota becomes KQQL, adopting an oldies format.
• September 22 – WYNY 97.1, a country music station and WQHT 103.5, a CHR station swapped frequencies in New York City.
• October 7 – WNBC radio in New York signs off for the final time at 5:30 pm after 66 years on the air, being replaced with an all-sports station, WFAN. The switch was the culmination of a complicated station owner/format swap initiated by Emmis Communications, owner of WFAN and FM sister WQHT; the latter switched dial positions with WNBC's FM sister, WYNY, which was sold off to Westwood One. The original frequency for WFAN was spun off to The Jewish Daily Forward and became WEVD.
• November 1 – KHTR in St. Louis, Missouri becomes KLOU, going from a Top 40 format to an oldies format.
