The graph provides an overview of the proportion of radio listeners and TV viewers aged over 4 in a typical day from October to December in the UK in 1992.
Overall, it is apparent that radio was most popular in the morning as people were getting ready to start the day, while TV viewership was highest in the evening.
In the early morning hours prior to 6am, TV and radio both had audiences of less than 5 percent of the population, with TV slightly ahead of radio. However, from 6am to 9am, radio listeners spiked, peaking at one quarter of the UK population. At the same time, TV viewers rose much less significantly, standing at around 7 percent at 8am. TV and radio viewer percentages then declined, with TV returning to its early-morning low, while radio listeners continued to drop so that by 3pm they were at half the level of their morning peak.
In fact, despite an increase of a few percent around 5pm, radio listeners continued to diminish throughout the rest of the day. On the other hand, from its 11am low, the proportion of TV viewers began to climb dramatically, overtaking radio’s popularity by 1pm. After that, TV viewer figures continued to surge. By 6pm, 40 percent of the relevant UK population were watching TV and this figure continued to climb to a peak of approximately 45 percent at 9pm, before a rapid drop-off began as viewership returned to its late-night/early-morning lows.
