Flow: An historically specific condition emerging in the late 60s, 70s when television programming moved to make the transitions between programs more seamless, (more entertaining advertisements, ads spread throughout the program rather than bookmarking it, announcements 'we'll be right back', extending hours of programming throughout the 24hr day, designing content to grab their viewer's attention early, trailers for later shows to keep viewers attracted). Content/Scheduling/Reception are all designed to enhance flow. "I'm not watching 'Starsky and Hutch', I'm watching television." Previously broadcasting programming would sequence their discrete units and the intervals were more apparent. Indeed, other leisure practices, concerts, theatre, sports matches, magazines are designed with miscilany for variety and a sense of 'flow' but they still constitute a single event. This concept speaks to Gitelman's extensive/intensive heuristic. (paraphrased from Raymond Williams, Television. 1975).
