The most important question - What part of South Jersey do we cover? (Are we talking WZBZ or WKMK or WCZT or WVLT or WJKS? All SJ stations!)
For the sake of simplicity, let's say I you give me WAYV, covering Atlantic/Cape May/Cumberland/Ocean counties with a nice strong signal...
Assuming 1) Sales don't matter, 2) Money doesn't matter
I take it very cutting-edge Top40/Rock hybrid.
Hire a huge morning show, kind-of a cross between MMR's Preston & Steve and JSE's Morning Edge.
Market the heck out of it, incl. billboards & TV ads on Cable in all 4 counties.
Have a promo team everywhere, at every large summer event in the 4 county area and even a bit outside of it, ie: Susquehanna Bank Center/PNC Bank Center.
Have the promo team at select Eagles/Phillies/Flyers/76ers games.
Have a contest like 106.3 The Shore had with a "Sticker stalker" prowling the streets for bumper stickers on the GSP, Expressway, Rt. 40, Rt. 30, Rt. 70/72, Rt. 37, Rt. 55 etc.
Have hourly traffic, news & weather updates, but presented in a quick, condensed, non-boring way.
Have a summer concert series with 1 in Wildwood, 1 in Atlantic City and 1 in Seaside.
Hook up with some local High Schools and Colleges to let students get on-air and program an hour during the overnights.
If anything it would make people remember the station!!!
