Warner Brothers was founded in 1923 by four brothers in Hollywood. It became famous for releasing the world's first "talkie" film, pioneering synchronized sound in movies. Since then, Warner Brothers has built an impressive legacy of high-quality entertainment and technological innovation, creating a diverse catalog of over 61,000 hours of programming including 6,500 feature films and 3,000 TV shows. As a global entertainment company with over 20,000 employees operating in more than 30 countries, Warner Brothers continues to produce around 18-22 films per year that are distributed internationally, generating $5 billion at the global box office in 2013.
