In this paper, we discussed convergence in terrestrial broadcasting and wireless communication with respect to technology and service models. Especially, retrieval and relocation of TV broadcast spectrum after upcoming D-TV transition is investigated so that the benefit for broadcasting and communication industries as well as spectral efficiency to be maximized. Also, the role of TV broadcast spectrum as a utility for convergence of two industries is investigated based on open spectrum, open platform and open application initiatives.
