An honorary production company of a film or television series refers to a company that specializes in producing the film or television series. It is usually composed of some famous film companies or television production companies. They may own the copyright of the film or television series but will not directly participate in the production or performance. An honorary production company would usually provide an official recognition mark to the audience to represent that the production quality of the film and television series was high and had been recognized by the industry. The production company could also receive certain tax concessions when the movie or TV series was released, as well as some support in publicity and promotion. Therefore, an honorary production company was usually a production company with a good reputation. The quality of the films and television dramas produced by them was also relatively high and had a certain degree of influence.
