"WRVM was 680's identity between 1957 and 1965. The 250-watt daytimer started out in 1946 as WRNY. The flip to WRVM brought the first top-40 format to the market, and at least one future big name: Johnny Holliday, who's now a big name on the DC sports scene"
He's now the voice of the University of Maryland Terrapins (he's called at least on Terps run to the NCAA basketball title so far, IIRC). Not to mention the last music personality who ever spun a record on 1010 WINS in New York, the evening before they went all-news in April of 1965.
"In 1965, WRVM became WNYR, the market's first country station - and 15 years later it moved up the dial to full-time operation on 990, where it went through lots and lots of callsigns (can I remember them all? Let's try: WNYR, WEZO, WRMM, WCMF, WDCZ, WLGZ, WRCI, WDCX!) on the way to its present religious format."
Very successful at the country format as "Winner 68" for a lot of years...and also had a strong news department, unusual for a daytimer (although WNYR's strong showing was also unusual for a daytimer in a top 50 market). Jim McLaughlin, later a news star in Buffalo at WKBW and WBEN, was WNYR's first news director back in 1964. My former colleague Mark Giardina later served as ND once WNYR went to 990 and 24/7 operation. That should tell you WNYR was serious about news, and brought in talented people to present it, for a long time, from the 60s deep into the 80s...
