This document discusses television scheduling and ratings. It explains that programmers schedule shows according to lifestyle factors like children's shows in the morning and prime time in the evenings. Ratings data is collected by BARB to determine viewer demographics and profiles for each show. Poor ratings can lead to shows being cancelled. Advertisers use ratings data to determine when and where to place ads. Programming and advertising aim to appeal to stereotypes to make shows easy to follow for audiences. However, television often simplifies or leaves out facts due to biases.
