You don't have to be collecting a check in radio to understand that format changes are never about ratings or programming success. In today's world it is ALL about sales. I'll bet that with two other AM talkers in the market (the 900 lb gorilla WOND and Hurley's WPG) WIBG was seeing revenue drop every month. The Atlantic/Cape May market can't support two AM talkers, let alone THREE.
Right now in the market (Southern NJ/Philly) there are at least 5 talk options, all well supported. The market is no worse for talk than for music, if its done well. As for ratings/success/sales - these are not independent of one another they go hand in hand. At the beginning of 1020s talk format change in 2011 they had a ton of advertisers but their follow up was poor and their programming didnt offer enough variety. When you look to Don Williams who is willing to change it up with live remotes and guest interviews you see what 1020 talkers were doing wrong. Advertisers want to see that you have a strategy for pulling in new listeners so that there are ears on those ads, which is what the M-F hosts never did - they got those 25 callers/repeat callers and were happy with that, harped on the same issues day after day. When you feel that the 900 lb gorilla is the long in the tooth WOND and you don't see that as an opportunity - imho that is a management flaw. As for Hurley - he succeeds with revenue because he does a lot of infomercial type shows that are guaranteed $$$. But do you listen to infomercials? I don't.
EnVivo is not good its just new. There are several Spanish language options in the market.
