The Clear Channel cuts were across the board. Yes there were a lot of afternoon people let go. But also middays and even some morning people were cut.
I assume the morning people will be replaced, especially if the person let go was earning a lot of money. In that case, they'll simply put a low-wage DJ on who'll do a mostly music morning show. Or in some cities, a two or three person morning show will continue with one less person.
Outside the largest markets, many radio stations these days ONLY have a morning team, midday person and afternoon person on staff. Overnights are often not even voice tracked. They just play music, spots and jingles. Many stations don't even prerecord the weather. And evenings get a syndicated show, or are voice tracked.
At my first job in FM radio, the station had a DJ on duty 24/7. You could hear a live weather report or call in a request at 4am Sunday. Today, there are still a few stations, even outside the largest markets, where there is a live DJ around the clock. But they are increasingly rare.
I also have to think back to the 80s when satellite delivered formats started to become popular. You didn't need to have your own DJs when you subscribed, except for maybe your own local morning show, or maybe not. The DJ in Dallas or Chicago would make simple chatter between songs and most listeners never knew he wasn't at their local radio station. But only the smallest markets used these services. Now with so many stations, even in big cities, cutting their DJ staffs down to three or four people, I wish stations would start using satellite programming, just so the hours between 7pm and 6am aren't simply music, spots and pre-recorded liners, with no live voice heard.
