Throughout this period it was considered socially acceptable to screen anime for an audience without consent as few companies had American offices, and of the few that did, the answer was invariably "no". Japanese companies made it apparent that they knew fans in the United States engaged in unauthorized distribution and screening, however knew that fans were not profiting. Japanese companies asked fans to help them publicize, for instance, Toei Animation asked the C/FO to aid it with some marketing research at San Diego Comic-Con. Starting in 1978, Japanese companies tried to set up their own American divisions; however, with the exception of the film "The Sea Prince and the Fire Child" which was licensed to RCA/Columbia Pictures Home Video, they realized they were not going to succeed in the American market and the last American anime company branch closed in 1982.
