Well, many quality engineers, once a full-time staple, were replaced with contract engineers. They were the 1st to go. Many of the better ones became Independent Contractors themselves, especially if they were good at problem solving or running interferece (pardon the refernce) with the FCC for smaller operators. Some went to great careers with the Phone Company, satellite firms, cellular phone services, security services, one I know just retired from the current incarnation of Muzak with a nice pension.
Some DJs went to clubs, where they were already suplimenting their income anyway. A few smart ones focused and teamed with wedding/party planners and earn a nice income doing both events and clubs. But they don't look at it as pocket money, they take it seriously. Some created internet Stations, but few have figured out how to turn a profit. Royalties are real dollars.
Some sales people went into Real Estate or Auto Sales, both of which also fell on hard times. Some Internet sales.
The talent that was on-the-air for decades in the same community could still demand a nice check for voiceover work from home with a simple AT-2020 kit plugged into the USB port to record! $149 from BSW. And it sounds better than the $600 EV they used at the station.
Some took anything to put food on the table that was honest work.
