The line graph illustrates the percentage of the UK population over four years old listening to the radio and watching television throughout a typical day between October and December 1992.
Overall, radio and television audiences follow distinct patterns. Radio popularity peaks early in the day, while television viewership experiences a substantial surge during the evening, becoming the dominant medium for the majority of the day.
Radio usage begins at approximately 3% at 1.00, rising steadily to a peak of 25% at 9.00. Following this morning high, radio listenership gradually declines, dropping to 15% by 13.00 and reaching a low of 4% by 21.00. Conversely, television audiences remain relatively low during the morning and early afternoon, hovering between 3% and 7% until 11.00.
From 13.00 onwards, television viewership increases sharply, matching the radio audience at 15%. It continues to climb, reaching a significant peak of 45% at 21.00. Although television figures begin to fall after this point, they remain at 35% by 23.00, which is considerably higher than the 5% recorded for radio at the same time. In contrast, radio maintains a minor secondary peak of 13% at 17.00 before falling away.
