Yep, WINZ was one, if not the 1st NIS station not in NY. While at WINZ Dick Casper helped create it and took it with him when he went to WNWS (790), which did irritate Guy Gannett ownership a lot, but not for long.
Since there are discussions of who owned what, There was a WINZ, WINZ-FM (but not on 94.9) and WINZ-TV. The TV (channel 39) didn't work out and signed off. A little piece of trivia, WINZ was caught up in the TV Quiz show mess of the mid 50's. It was owned by host Jack Berry and the FCC created enough pressure for Berry to sell. WINZ later made news when they stole Cousin Brucie from WINS to replace Bob Green, who decided he wanted to "pursue" Anita Bryant.
