It's true, that change of some kind is inevitable. It'll be unnoticeable to the audience that listens, but changes WILL start to happen after the sale takes hold. Small things at first - an employee who worked at WBEB perhaps because he or she didn't want to work for a big corporation might decide to move on somewhere else. This creates a hole that needs to be filled, and Entercom will need to fill that hole. It might be in an on-air-invisible position like in the business department or HR. Or, Entercom will want to oversee its new possession, so someone from the corporation will be assigned to the WBEB location to keep tabs on the goings on. Eventually more and more of these job openings will be filled by Entercom employees doing the hiring. Music selections and on-air presentations will remain untouched for a long time, but eventually, you'll notice something's different there too. An attempt at some point to cut costs will lead to an on-air position to be eliminated. It may not happen for a few years, but it will take place at some point. Then there's the location. Will Entercom ever try to consolidate its station locations into one place? Just to save on electricity? Rent? Engineering requirements? Those things usually take a number of years to happen, but those kind of changes DO happen. You're not supposed to hear any difference, but some small things might change. Will they relocate in the city? In Bala? It makes a big difference in employees' outlooks. Big city wage taxes and maybe big parking problems in center city take a toll on employees.
It's impossible to predict the future, but I just wanted to point out that some changes somewhere are inevitable. I've been through it. I've seen it happen.
