WMOZ was owned by Edwin H Estes. He also owned WPFA 790 in Pensacola, a country station. WMOZ, a 1 kw daytimer on 960, had incredible ratings, and was an easy sell to advertisers. The FCC was strict about 18 minutes per hour, but WMOZ was known to run way over the limit, then falsify the logs submitted at license renewal. Even heard one story where a DJ died in between the date of the log and the time it was submitted for license renewal, so his signature was forged.
It ain't smart to forge a dead man's signature when you are in competition with another station that is sitting there taping you and counting your spot load.
Back then, the FCC randomly picked out a Sunday, Monday, Tuesday (and so on) from the 3 year license period, and you submitted the logs, and a composite total showing the 18 minute limit was not exceeded.
The Estes licenses were revoked, and 960 fell silent, much to the joy of WGOK 900, the other black daytimer, around 1964. Within 2 years, WMOO 1550, which came on the air in 1964 as a country/gospel mix, began to block program black, and eventually went totally into the format, hiring Sugar Daddy (Ruben Hughes) Poppa Rock (Jordan Ray), and Deacon TJ McClain (host of the Gospel Train) the 3 personalities that made WMOZ so dominant. This was 1967, though they still had some paid religion blocks midday bcuz the money was too easy and too good to pass up.
No less than FOUR applicants applied for the 960 frequency. One was Howard Smith, owner of WLPR FM 96.1 (I worked for him from 1965-67). He wanted to have 96 FM and 96 AM. The hearing went on for 20 years, by which time the applicants had all spent more in legal fees than the facility was worth. Howard ended up with the station, 5 kw D/1 kw DA-N (two towers) in 1986, long after he had sold off WLPR. It came on the air as WGRR, airing the satellite fed STARDUST format; by 1987 the WLPR call letters had moved to 105.5. When 105 gave them up, the Living Presence Radio calls came to 960 AM. The night signal took a beating from WERC Bham, whose main DA-N lobe came directly toward Mobile. I believe the station is now a daytimer, co-owned with 840 AM.
On the other question, a history of top 40 in Mobile: the first station to go at it was WKAB 840, a daytimer, around 1956. The Dittmans acquired WABB around 1959, and turned it into a great top 40 station. I always understood they came here from Cleveland, and copied WHK-1420, that market's leading purveyor of the format. I know the two stations' published Top 50 lists were identical in design, and they had the same jingles.
WKAB hung on by being more music intensive (they couldn't sell enough spots to be otherwise). Around 1962 they changed calls to WTUF Tough Radio, and hired a PD who had been at KAAY Little Rock. At sign off time they told listeners to tune over to their "sister station" on 1090, which not only put a very listenable night signal into Mobile, but it was the alternative in parts of west Mobile that WABB's DA-N didn't handle too well.
You gotta remember that in the 60s, Mobile had THREE fulltime stations, 710, 1410, 1480 ... and a half dozen daytimers. A fulltimer was a license to print money. Never mind that similar-sized cities like Chattanooga, Jackson, Baton Rouge, Shreveport, had 5, 6, maybe 7 fulltimers ... Mobile had 3!
WKRG 710 stayed MoR/CBS; 1410 as WALA had been MoR, but tried top 40 for a while in 1960/61 (I have a published weekly top 40 sheet from them in that era). Then the AM and TV were sold separately, and the new 1410 WUNI went country with great success. That's how it should be: at night, you had one top 40, one country, and one adult good-music station ... each had its own niche. So except for a little WNOE/WTIX day and KAAY night, 1480 had the format all to itself once WTUF gave up and went country, maybe 1964.
We actually listened to WNOE/WTIX more heavily when we went to the beach ... Dauphin Island or Gulf Shores ... we lost WABB before we got there, partly because of poor ground conductivity, and also because WGNE 1480 Panama City, traveled a salt water path and mowed WABB down.
WLIQ 1360 tried top 40 for a while around 1966, but it never went anywhere. WABB just kept on kicking ass. Not only did they have a format exclusive, but the black stations, WGOK, WMOZ, and later WMOO, were all daytimers, so the significant black population had nowhere to go except WLAC Nashville after dark. It was not unusual for WABB to have 60% night shares, as they played enough black music to hold onto both races.
I was overseas in the Navy 1968-71, so don't know much about what happened during that time ... then went to Jackson Miss for the rest of the 70s. WKRG FM was running the Drake Chenault Hit Parade format, which may have siphoned some of WABB's audience, but was not direct competition. That started about 1968. Around 1971-73 the 3 kw FM in Bay Minette went black, WWSM, and despite a signal problem in Mobile, it made a showing at night... until WBLX blew the doors off that compartment.
WTUF 840 had become WMOB when some people from New Orleans bought it; it was MoR. WMOB got the CP for 97.5 but couldn't go thru with it, so WABB bought it, and WABB FM AoR was born, about 1974.
Finally in 1978, a hot-shot from Dallas who had worked at KLIF came to GM WKRG AM/FM. By then, every other market had realized FM penetration was such that you could kick an AM's ass big time, so WKRG G-100 went for it (didn't you wonder when someone was going to finally realize that?). For the first time in 20 years, WABB 1480 knew what real competition was, and I vaguely remember the ratings showing G100 trouncing them, convincingly. The retaliation was to turn WABB FM 97 top 40, and in a few years they turned things around ... I don't think the owners of WKRG FM were committed to seeing the format through, so they evolved into AC (they were more comfortable with those demographics, and it complemented the AM's demos). That happens sometimes when you have a TV, AM, and FM ... and most of the attention was paid to the TV monster anyway.
WJLQ Q100 Pensacola was doing top 40 about this time, using a TM automated format. It was on a 500 ft tower in Fla, so its success was confined to Pensacola (except for maybe a 3 share in Mobile) until it went on a TV tower in Baldwin County around 1985. It was somewhat confusing when you had Q100 and G100 (100.7 and 99.9) as dials were analog back then.
The more recent history you all probably know better than I do. It says a lot for the Dittmans that they have owned the WABB (am/fm) calls for 51 years now, and have dominated the contemporary music arena the entire time except for G-100's heyday , maybe 1978-82. It's a far cry from that pitiful 5 kw AM that barely serviced Mobile, as the FM now shows up in Biloxi, Mobile, Pensacola, and Fort Walton Arbitrons.
