This was brought up by Bilbo in the "Is radio really this bad?" thread several weeks back.

"Well, this is from 2019, but study from Westwood One showed overnight (midnight - 6am) represented less than 5% of radio listening:

The 5% blew my mind and yet, there are ads running (IE WBBM-AM) and I'm sure, stations with NO ads. In addition to Commercial Free hours, Sundays, etc...

Might it make sense to sign off at Midnight-1AM and sign on at 5AM? (WBBM goes live at 4:30AM, so that must mean something!)

Some of these stations, I'm sure, have horrid AM signals and the possible FM translator adds squat.

With power bills, streaming, music licensing costs, etc., MIGHT it make sense to carve a little time out. 4 hours a day times 7 days = 28 hours of cutting prices.

Too, there are TV's on 24 hours.
It isn't 2005 or even 2020 anymore and things have been impacted. We all shop different, consume different, etc.

WKBM WNVR WJOB WSBC WWCA WBIG WKTA WEEF WRLL WEUR
possibly, my list.

Stations really went 24 hours after 9/11.
After loss of revenue/etc., from Covid, might it make sense to cut back?
