The graph illustrates the percentage of the UK population aged over four who tuned in to radio and television throughout the day in the last quarter of 1992.
At the start of the day, around 6:00 AM, radio listeners outnumber TV viewers, with radio capturing roughly 5% of the population while television usage is negligible. Radio audience size rises steadily, peaking at just over 25% at around 8:00 AM. Conversely, television viewership starts to climb around 8:00 AM and continues to rise until it reaches a significant peak of approximately 45% at around 9:00 PM.
Throughout the day, the radio audience sees a gradual decline after the morning peak, dipping to about 10% in the early afternoon and maintaining this level until the evening. In contrast, television viewership sees a slow and steady increase from midday onwards. It surpasses radio audiences by the afternoon and continues to climb sharply in the evening, peaking in the late evening hours.
After the 9:00 PM peak, television viewership declines rapidly, dropping back to around 5% by midnight, and then remains very low throughout the early morning hours. Radio usage also decreases in the late evening but experiences a slight rise at around midnight, before returning to minimal levels similar to early morning TV viewership.
In summary, radio is most popular during the morning hours, while television dominates the evening hours. The afternoon sees a more balanced distribution of audiences for both media.
