If you go to Citadel's website, it will redirect to the Cumulus website. Cumulus is the first company outside of Clear Channel that takes over the Citadel stations including WABC and WPLJ. In the past, it was ABC Radio, Disney, and then Citadel. But now Cumulus is the next big thing. In addition to the two NYC stations that Cumulus now owns, it owns many of the stations in the Hudson Valley including WPDH, WKXP & WZAD's "The Wolf", WCZX's "Mix 97" and WRRV & WRRB are the 6 stations in the HV listening area outside of New York City as well as the three AM stations are WALL, WEOK where they both carrying Scott Shannon's "True Oldies Channel" and WKNY. That brings to a total of 9 stations that Cumulus owns and two big NYC stations that now owns are WABC and WPLJ.
I was listening towards the top of the hour that WABC mentions "A Cumulus Media Station" or shall they call it "A Cumulus Broadcasting of New York Station". That fits really well.
