The graph illustrates the percentage of the UK population over 4 years old who listened to the radio or watched television at different times of the day from October to December in 1992. It is evident that television constantly attracted larger audience than radio for the majority of the day, with the most striking feature being the television hitting a vertex particularly in the early evening.
On the other hand, radio listenership culminated in the early morning, reaching just roughly 35% over the period between 6 and 8 AM. Following this, radio audiences sequentially declined to around 10-15%, for the rest of the day, with a slight surge just after noon. Conversely, television viewership started at a low level early in the morning and touched the highest point moderately, experiencing a tedious increase around midday. The audience then surged dramatically in the early evening, reaching a vertex just beyond 50% between 6 and 8 PM. After this peak, television viewership sharply waned through the night, plunged to minimal levels past midnight.
In summary, the graph clearly illustrates the divergence in consumption patterns: radio was most popular during the early morning hours, maintaining a oscillated audience in the daytime, while television dominated in the early evening viewership, capturing the largest percentage of the population at the time.
