Herbert Bulmer described audiences in 1950 as having four key characteristics: 1) being composed of individuals from all social backgrounds, classes, occupations, education levels, and wealth levels, 2) being anonymous groups of anonymous individuals, 3) having little interaction or shared experiences between members who are usually physically separated, and 4) being loosely organized and unable to act with the unity of a crowd. Julian McDougall believes this view is now outdated given online audiences are harder to define as stable groups. However, audiences still provide meaning to cultural works and can be seen as "temporary collectives".
