Sept 14 (Reuters) - Walt Disney Co (DIS.N) has held exploratory discussions about selling its U.S. TV network ABC to regional TV station operator Nexstar Media Group Inc (NXST.O), people familiar with the matter said on Thursday. Nexstar's interest is preliminary and may not lead to any deal, one of the sources said. Nexstar and Disney did not immediately respond to requests for comment. Disney's ABC comprises a national television network and eight regional stations. It also has affiliation agreements with about 240 local television stations reaching almost all U.S. television households.
