The TV audience curve refers to the fluctuation in the number of viewers watching a television program over a specific period of time. It is a graphical representation of the audience’s interest and engagement with a particular show, starting from the beginning of the program and ending at its conclusion. This curve can vary depending on various factors such as the time of day, day of the week, and the popularity of the show. It is a crucial tool for broadcasters and advertisers to understand the viewing patterns of their target audience and make informed decisions about programming and advertising strategies.
