There should be more about how George Storer bought 5 kw daytimer KPOP and spent most of the 60's upgrading it and changing formats... including the flash success of Bill Ballance going into the 70's.
@DavidEduardo, going back through Broadcasting archives at worldradiohistory.com (I need to buy the fella who runs that thing lunch someday), it looks like the previous owner had an application for the power increase on file when Storer bought it from them in spring of 1959 for $900,000.
The first format was Beautiful Music, and they ran with that until 1964, but could never make meaningful headway against the longtime leader, KPOL.
They went Country in 1965, then *sorta* Top 40 in 1969---in that the music was arguably Top 40, looser than KHJ, but still---and the jocks were (mostly) big-name Top 40 jocks in the market from the past decade---Emperor Bob Hudson, Bill Ballance, Roger Christian.
Lightning struck in 1971---yes, Bill Ballance started the "Feminine Forum", but, because of the popularity of their standup act and record albums, KGBS moved afternoon jock Ron Landry to mornings to team with Hudson---and Hudson & Landry were a legitimate factor in morning ratings, followed then by Ballance, and (after moving Landry), Dave Hull, who until The Real Don Steele showed up, had been the number one afternoon jock in L.A.
Even after the novelty of the Ballance show wore off, the bookends of Hudson & Landry and Dave Hull was a big draw for young adults (18-34) who had aged out of KHJ, but weren't onboard with the album rock of KLOS or KMET.
It started to lose altitude in '73 and by early '74 it was over. They really needed a night signal, but as KTNQ shows, even that wasn't enough.
