While there are a number of legal considerations with starting such a business ranging from setting up a proper entity, to IP concerns and managing content providers, employees or independent contractors among others, I do not know of any specific license required in NJ for this. Typically, when you create an entity in NJ you also register with the tax division and there they will ask that you identify which type of business you are operating at that time. Of course, it is always a good idea to cross your Ts and have a professional look into any possible compliance requirement. This is fairly routine when we set up the business structure for our clients.
I would suggest that you discuss your plans with a lawyer in private so you can get some guidance here. Most of us here, including myself, offer a free phone consult so you may wish to take advantage of that.
