"Oldies" in radio-insider-speak is a 60's music based format, with perhaps a smattering of 50s and a bit of early 70s'. "Classic Hits" is the format that plays the same kind of music, but mostly 70's with even a little 80s thrown in.
Those are terms used inside the industry, while on air, a station that is classic hits may call itself "oldies."
Generally, most former oldies stations have changed to classic hits in the last few years, because the audience for oldies was becoming predominantly over 55, and there is little interest from the larger ad agency type advertisers in this audience.
Classic hits appeals to motly a 40-something core, and is very attractive to advertisers.
I hope that clarifies the "insider terms" for you. And it is surprising that there not be a classic hits station in Houston... given the success of stations like KLUV in Dallas and KOOL in Phonenix, two large markets in the Southwest.
And to clarify further since you're out of the market, David: 107.5 transitioned from oldies to Classic Hits several years ago before it dropped the KLDE calls for KHTC (K-Hits). For its last year or so as K-Hits it played mostly 70's music with the occasional 60's song. As KGLK, it dropped all 60's titles completely (maybe there's one Stones song from '69 in there) and now is 50/50 70's & 80's, with music from 1970 to 1989. It's still a Classic Hits station. Ratings-wise, it has outperformed K-Hits.
For the longest time, 107.5's biggest problem was that the audience was still recalling them as Oldies 94.5. They did a good job of establishing the Oldies 107.5 brand after that - such a good job of it that once it became K-Hits, people still considered it to be Oldies 107.5. It's interesting to note that the station had stopped playing oldies titles for months as K-Hits (not a single Motown hit was heard, but a whole lot of Steely Dan & Led Zepplin), yet it wasn't until the imaging change to the Eagle that people like the above listener finally figured out that this was no longer the station that played You Can't Hurry Love.
And to you, I'm sorry that you don't hear your favorite songs on the radio anymore. Most of my favorite radio stations don't exist anymore either (and those that do, only the call letters remain anyway). But please don't damn me to Hell because I had to put food on my table. It may be fashionable to rip on "Corporate Radio," but there's several hundred people in this town who work for those corporations and live next door to you, and we're all just trying to pay our bills, go to church on Sunday, and raise our families.
