During the mid-1980s, the Top 40 format, which had disappeared from radio dials in many cities, regained popularity. Birmingham had one Top 40 station, WKXX (now WBPT). In 1984, the album rock format was dropped in favor of Top 40, first calling itself "95 FM". By the end of the year, WAPI-FM was re-launched as "I-95", calling itself "Birmingham's Hit Rock". Within a year, I-95 had replaced WKXX as the dominant Top 40 station in Birmingham. The most notable announcers on I-95 were Mark Thompson and Brian Phelps, who first teamed at I-95 before moving to KLOS in Los Angeles in 1987.
