I have always found it interesting how Jackson never had an alternative station. The Gulf Coast could easily receive alternative stations from Mobile and New Orleans AND had their own alternative-leaning active rock station (WCPR). CPR did not just "survive" in this market, the station thrived by consistently ranking in the top 5 and occasionally beat country stations K99 and Kicker 108 in the male 18-34 demo. While CPR reported as an active rock station, the playlist included many alternative acts outside of the active rock format such as Tori Amos, Jewel, and Folk Implosion.
I was puzzled that a station owner in a different market didn't observe this and flip an under-performing station to this format. As I learned at the time, the alternative is not easily marketable to advertisers especially in a small Mississippi market. While the alternative fanbase comprised of loyal teens and 20s males, small businesses didn't consider this to be a lucrative demographic. CPR's ratings success meant that it was easily awarded national advertising contracts and did not have rely on attracting local advertising revenue.
Radio formats were marketable in this order: 1) Country 2) Urban AC 3) Hot AC 4) Classic Rock and everything else including CHR, gospel, active rock, talk, and sports talk scraping the bottom.
Another problem may have been the nature of the alternative format itself. Unlike other formats such as country, AC, and Top 40, the charts for the alternative format were more rigid. There were major inconsistencies among the alternative playlists across the country. Some stations played obscure and edgy tracks attempting to position themselves as a commercial version of a college station. Others opted for a more conservative playlist that only include "safe" tracks from established artists like Soundgarden and Alice In Chains. Also, it was a common practice for some stations to cherry-pick artists while ignoring selectively others that deemed to not be a "good fit" for the station or the listening audience. An example were Seven Mary Three that sounded too similar to Pearl Jam according to many station PDs.
This means that alternative stations required significant investments in program directors, music directors, and other human capital. Success could not be achieved by simply programming the top 20 songs in heavy rotation like a country or contemporary format. This lack of national playlist consistency may also explain why Westwood One and Jones never launched satellite-fed networks that some stations in Mississippi may have considered affiliating at the time.
Also, alternative stations had to invest in marketing to create a buzz (no pun intended) to build brand and listener loyalty. CPR, The Zephyr, and many other stations did this by hosting concerts and festivals like CPR-Fest. All of this investment and overhead meant that the alternative format was very expensive and the revenues were uncertain. Many station owners considered the format too risky and unproven.
The situation in Jackson is even more interesting. A rumor circulated that an under-performing station (98.7 ?) was considering a flip to alternative. Since Jackson had a classic rock station called ARRO 94.7, Z106 saw this as an opportunity to position the station as the dominant active rock/alternative leader by launching Planet Z and adding alternative tracks into the regular playlist. This may have prevented this unknown station from launching.
Even though there was no full-time commercial alternative station in Mississippi, alternative music did receive a lot of airplay on many stations. See the list below:
Tupelo:
KZ 103 had a nighttime alternative show
Columbus
WSMS (The Storm and later The Fox) had a weekend alternative show and later added alternative hits into regular rotation after transitioning to The Fox
Starkville
WMXU (Mix 106) included alternative tracks into regular rotation
Jackson
Z106 had Planet Z as mentioned
Hattiesburg
SL 100 regularly included alternative hits in nighttime rotation and had a weekend alternative show
Zoo 107 had a weekend alternative show
Y 104 included alternative hits in regular rotation
Let's not forget our college stations...
WUMS (Ole Miss) and WMSV (MSU) were full time alternative stations
WUSM played underground alternative during the overnight hours
And then there are the stations from adjacent markets that covered large portions of the state like The Zephyr in New Orleans, New Rock 107 in Mobile, and 96X in Memphis.
Now the format is dead and any remaining alternative stations barely survive only by rotating the safe, overplayed alternative hits of the 90's from Oasis, Nirvana, and NIN with the occasional post-2000 song thrown in. This is a shame because many recent acts like Muse and Cage The Elephant receive very little airplay but could benefit the alternative format tremendously.
