the American film industry
Hollywood is a district of Los Angeles where much early film-making took place. It is now an area where few studios are found. But the name has become synonymous with the manufacture of entertainment movies in America (and even other countries). Thus, ‘Hollywood’ extends to TV, advertising, and other media and exists in opposition to American ‘independent’ film-making (cheaper, less glamorous, more personal) — David Thomson
