The listeners did NOT necessarily go away by their own choice. CBS-FM had huge numbers (as an example) and yet they flippped it to Jack. Hence, more oldies listeners that went away. Not by the choice of the listeners, but by the choice of corporate.
Station managements do not change formats at the drop of a CD. They put plenty of thought into it. After all, not only do they have to think about new airstaff, but they have to have a new logo drawn up, design a new advertising campaign to reach the listeners they want, design new marketing materials to reach the customers (advertisers) they want, and then wait while they lose the listeners and possibly the revenue they had.
One example is Bonneville. When they owned 96.5 KOIT and 95.7 KKDV "the Drive" (aka KZBR "the Bear", aka whatever) they first tried to position 95.7 to be the male complement of KOIT. KOIT was heavy in women, which was very good for them, and they figured if they could sell KOIT and 95.7 as a package to reach total adults 25-49, they'd have it made.
But KKDV didn't work. So, they reluctantly changed format and offered KZBR, a country format targeted not to men but to women. Their strategy became, "Well, if we can't get women and men to sell together, let's get as many women as we can." Thus, KZBR leaned heavily on music that appealed to 25-49 women who weren't into KOIT.
The change from KKDV to KZBR required everything I said: logo change, ad campaign change, and a different approach to advertisers. That change cost them a lot of money.
They gave it a noble try but it didn't really work, either. So, they changed to another format and then swapped stations with Entercom.
Now, Entercom comes back with another country format on 95.7, and I'm not privy to what their target demo is, but I'm sure there's a strategy just as valid in making still another format change for 95.7.
As I said, it's expensive to change formats. So, if it's not broken, management does not usually go about fixing things. They just pray that nobody breathes too heavily and knocks down their house of cards. Formats are changed because the previous format was not working -- the station was unable to get the demos they wanted or advertisers balked at the format for whatever reason.
