For the most part, the Friday/Saturday night club mixshow/scene on the radio is done with. They still exist in major markets that have the budget. It worked for us. We would have a jock at a club doing a remote with cut ins while we had a live jock in the studio playing the mixshow.
The Saturday night show on the CHR station I programmed at the time disappeared almost 15 years ago. We had some syndicated request show shoved down our throats instead because "corporate wants more clearances". That was it. It never came back. The other part timers on the weekend disappeared soon after.
Very few stations are live and local on the weekends. Take a look at the lack of syndicated mix shows available now. It's because the demand disappeared. Yes, Hotmix and other shows are on many stations. It's far less than it used to be.
We had a local club dj that did a show for us Fridays in drive time. It was one of the first things to be cut in the budget. I was told that if I wanted a mix show on the station, I'd have to mix it myself. Local mixers were a pain because they never stuck with the playlist. I gave up on it.
