There are four main types of cinema audiences: mainstream audiences who prefer familiar genres like comedy and action and avoid foreign films; mainstream plus audiences who are drawn more to the nature of films than nationality but mostly watch American films; aficionados audiences who enjoy specialist films with unfamiliar casts but also tend to avoid foreign films; and film avids who appreciate films for their cultural morals and enjoy the cinema experience without preference to a single genre. Different methods of watching films appeal more to certain target audiences: teenagers prefer watching online due to control options, adults find DVDs more convenient to watch repeatedly, and teenagers and young adults are most interested in the social and 3D experiences of cinema.
