I don't remember exactly who used whom, but the company you're thinking of is Liquid Compass. I believe Liquid Compass, Triton, and Stream the World are the same company now. Seems like Stream the World and Triton merged, and Liquid Compass is now the name of the combined company's analytic arm. Triton Digital was recently acquired by Scripps. Most of the companies we were using in the early days of streaming are gone, whether through acquisition or just having folded. Real Networks is still around, but it's focused more on subscription based streaming. I haven't used Real Audio in a dozen years.
I always thought Susquehanna and ABC fit each other like a glove. When the Telecom Act passed and that seemed a possibility, Cumulus was barely around as its predecessor only had stations in Atlanta, Toledo and Nashville. That Cumulus would arise out of that small company and be the one to make it happen still seems almost surreal.
Although it was nowhere near the monster Cumulus was, I'd always heard Citadel was really bad after Larry Wilson sold the company to Forstmann-Little and left. My friends at my local Cumulus cluster tell me it's a lot better of a place to work now than it was when the Dickeys ran it. The corporate cramdown isn't nearly bad as it was, but it's not dead either. Budgets are better than they used to be, too, but nobody's getting what they got prior to the Great Recession. Going back to the local cluster, every music station was live 6 AM - 6 PM, and two stations were live 6 AM to midnight until October 2008. None of the nighttime and midday shifts that were cut have ever come back, and, despite better budgets today, they're not going to be back anytime soon.
