When we write music or jingles for you, we license the commercial to you directly. (This is less expensive than to sell you the copyright outright). Our standard term is included in our quoted price to you, and is for two years per station. After this time you have the automatic option to renew so you can continue with your existing advertisement if you wish. Our experience is that most clients feel ready for a newer commercial by this time, and of course we're happy to help!
