The year 1994 in radio involved some significant events.
- January - WHTZ Z 100 Newark, NJ/New York City modifies their CHR format by mixing large amounts of Modern Rock into the format. They would continue this for over two years.
- January 11 – The Irish government announces the end of a 15-year broadcasting ban on the Provisional Irish Republican Army and its political arm Sinn Féin.
- February - WHYT Detroit evolves from Rhythmic CHR to CHR
- March - KFMH (99.7 FM) of Muscatine, Iowa, ceases its longtime progressive and alternative rock format on March 1. Two weeks later, the station's sale to New York-based Connoisseur Communications is completed; days later, the station's new country format debuts with call letters KBOB (to compete with the Quad City market's WLLR-FM).
- March 17 - KRJY/St. Louis flips from 1950s/1960s oldies to classic hits, branded as "K-HITS 96". They would later adopt the KIHT call letters.
- March 28 - After about a year of moving most of the station's personalities to then-sister KUDL and evolving their music, Kansas City's KMXV "Mix 93.3" officially dropped its AC format to go CHR/Top-40, returning the format to a full-market signal. After KBEQ dropped the format a year earlier, the only option for CHR/Top-40 was 107.3 KXXR/KISF with a transmitter about 40 miles from downtown KC. KISF would evolve to modern rock later in the year, with the shift completed in January 1995.
- Religious radio personality Harold Camping once predicted that September 1994 would see the second coming of Jesus Christ.
- April 15 – Roy Disney's Shamrock Broadcasting, which merged with Cleveland-based Malrite Communications Group's radio group in the previous year, spins off Cleveland stations WHK and WMMS to OmniAmerica, headed by former Malrite executives Carl Hirsch and Dean Thacker. WHK switches format to all-sports. WMMS' format moved to alternative rock, and the majority of the station's airstaff is replaced.
- June 25 - KXRX/Seattle drops its album rock format and begins stunting with comedy routines and an electronic countdown. On July 1, KXRX officially flips to Country as "Young Country 96.5".
- July 4 - WHYT/Detroit shifts to "Planet Jams", a hybrid Rhythmic CHR/modern rock format. The Rhythmic product would later be phased out during the year, resulting in the complete shift to modern rock as "The Planet."
- July 9 - The final original American Top 40 airs in the U.S. The show continues internationally only for six months.
- September - WLUM/Milwaukee, Wisconsin dropped its Rhythmic Contemporary format for Modern Rock as "New Rock 102ONE." The move left Milwaukee without a Top 40-based station until WXSS debuted in 1998.
- October 1 - WPAT-FM relaunches its Adult Contemporary format as more uptempo and now called Today's 93.1. WPAT 930 also simulcasts during the day during the week but runs leftover sports many evenings. WPAT FM dropped all weekend specialty programs except for Sid Mark's Frank Sinatra show. The AM retains the other specialty programming and Sunday morning public affairs stuff.
- November – After eight-and-a-half years on the air, 105.5 KNAC in Long Beach announced that they would be changing formats. The radio station eventually went off the air three months later (on February 15, 1995), and was replaced by the Mexican music radio station KBUE (Que Buena).
- November 14 - During an interview with ABC Radio, ABC News anchor Peter Jennings caused an outcry from conservative commentators and viewers when he made a statement comparing "angry voters" to two-year-olds with "uncontrollable rage" when asked about his views on the 1994 midterm elections. After petitions calling on ABC News to fire Jennings over these comments, and some asking that he be deported to Canada, Jennings apologized for the statement.
- July 15 – AFN Berlin says farewell to the public with a 3-hour special broadcast, transmitted live into 54 countries.
