No, not entertainment law. More like telecommunications, broadcast, TV and radio regulation, internet advancement and regulation, etc...
Yeah, but those discplines tend to be interrelated. Just pick one of the stronger entertainment law schools or a school with strong graduate communications and journalism departments. The latter could provide a clue. If the law school is good, chances are you'll get what you want. The entertainment law schools tend to be strong in media and communications law.
Start with UCLA, USC, CLS, NYU, Fordham, Loyola (CA), and Cardozo. I'm just guessing right now. I would also try Penn (the communications school there is supposed to be top notch), Southwestern (if you don't care about rank), and Duke.
Look in the specific law school guides and they will tell you how many courses you are available in the media and communications areas. The best schools are, unsurprisingly, going to be in Cali or NY - with a few exceptions (Duke, Penn, Vandy, Tulane, etc).
