The line graph illustrates the proportion of people in the UK over the age of 4 who watched TV and listened to the radio over 24 hours from October to December 1992.
Overall, a significantly greater percentage of the TV audience watched in the evening while radio had the most listeners in the morning. Over the course of each day and night, more people watched TV than listened to the radio.
Less than 10% of people watched TV between 1 am and 12 noon but at 4 pm this figure increased rapidly, reaching a peak of almost half the population at 8 pm. After this, the graph records a sharp decline in viewers, reaching a low of only a tiny percentage by 3 am.
Radio, on the other hand, shows a very different trend. The most popular time for listeners to be tuned in was just after 8 am when around 27% of the population was listening. After a brief peak, the numbers dropped steadily to barely 2%, apart from fluctuations at around 4 pm and 10.30 pm. The percentage of listeners remained low overnight before beginning a rapid ascent from 6 am to the 8 am high.
