The line graph illustrates the fluctuations in the proportion of TV viewers and radio listeners in the UK over a single day during the months of October to December 1992. The data, expressed as percentages, highlights that radio audiences were more prominent during the early morning hours, while television attracted a significantly larger audience in the evening.
Radio listenership began at a minimal level of around 6% at 6 a.m. and surged sharply over the next two hours, peaking at nearly 30% by 8 a.m. Following this, the numbers gradually declined, falling to just over 10% around midday. A minor rebound occurred at approximately 4 p.m., where the figure reached 14%, but listenership steadily diminished thereafter, dropping to its lowest level of 1-2% between 2 and 4 a.m.
In contrast, the percentage of TV viewers showed a consistent upward trend throughout the day, beginning at a lower point but climbing to around 20% by 4 p.m. It then experienced a sharp rise, peaking at nearly 50% at 8 p.m., a level that remained relatively constant until 10 p.m. Afterward, the viewership declined dramatically, falling to approximately 2% by midnight.
