The film industry made $10.2 billion in 2011 despite rising ticket prices. Comedies and adventure films were the most profitable genres between 1995-2011, with horror in seventh place grossing $9 billion. Horror films on average gross $28 million a year from about 20 releases, though only a few are major box office hits. To earn a good return, films need innovation, like Avatar's CGI or Paranormal Activity's documentary-style camerawork, which created fear without knowing if the film was real. Modern prominent horror producers include Wes Craven and Neil Marshall, while top distributors are Lionsgate and Paramount.
