Television studies is an academic discipline that deals with critical approaches to television. Usually, it is distinguished from mass communication research, which tends to approach the topic from a social sciences perspective. Defining the field is problematic; some institutions and syllabuses do not distinguish it from media studies or classify it as a subfield of popular culture studies. One form of television studies is roughly equivalent to the longer-standing discipline of film studies in that it is often concerned with textual analysis yet other approaches center more on the social functions of television. For example, analyses of quality television, such as Cathy Come Home and Twin Peaks, have attracted the interests of researchers for their cinematic qualities. However, television studies can also incorporate the study of television viewing and how audiences make meaning from texts, which is commonly known as audience theory or reception theory. History Charlotte Brunsdon argues that television studies is an "aspirationally disciplinary name given to the academic study of television." Since it is a relatively new discipline, Brunsdon notes that "...many of the key television scholars are employed in departments of sociology, politics, communication arts, speech, theatre, media and film studies." She argues that television studies developed during the 1970s and 1980s "...from three major bodies of commentary on television: journalism, literary/dramatic criticism and the social sciences." Critical methods for television have been "...extrapolated from traditional literary and dramatic criticism." Horace Newcomb argues that television studies scholars often need to justify their academic focus: "[T]he mere suggestion that television needs analysis itself requires supportive argument." As a result, television studies is marked by a great deal of "disciplinary hybridity." Perhaps because television scholars are approaching the subject from so many different disciplinary and theoretical perspectives, there are many debates about how television should be understood and conceptualized from a political and methodological point of view. Another impact of the disciplinary hybridity is the diversity in the types of studies carried out. Early television studies included histories of television, biographies of television producers, archival research by historians, and sociological studies of the role the television set played in 1950s homes. In television studies, television and other mass media forms are "...conceptualised within frameworks" such as "...ownership; national and international regulation of media production and distribution; professional ideologies; public opinion; [and] media audiences." As the field of television studies was being developed, it was influenced by the medium's
