The graph shows (relates) the percentage of radio and television audiences over 4 years old in the UK (the UK population over 4 years old who tuned in to radio and television) throughout the day from October to December 1992. The figure reveals that before 2:00 pm there were more radio audiences, while after 2:00 pm more people turned to television. There was a gap of 10% between radio and television audiences.
　　The data indicates that radio listeners increased (grow, rise, go up) substantially before 8:00 am, when the percentage reached (amounted to) to a peak of 27%.
　　The percentage then declined steadily to 11% at 4:00 pm, which was followed by a slight increase to 15% at 5:00 pm.
　　However, from then on, there was again a gradual decrease to 2% until 4:00 am, when the percentage bottomed out. The period from 4:00 am to 6:00 am saw another slight rise to 4% in radio listeners.
　　As for (similarly) TV viewers, the percentage went up from 6:00 am to 8:30 am, when there was a leveling off at 8% until 10:00 am (for the next one hour and a half)
　　After a slight decrease, the percentage rose sharply to 15% between 12 pm and 2 pm, before it dropped slightly.
　　The peak (45%) was reached at 8:00 pm after a massive rise from 14% since 3:00 pm.
　　However, the period between 8:00 pm and 3:00 am saw a slump in television viewers. The percentage reached the bottom of 3% at 3:00 am, when there was a slight rise afterwards.
　　The general trend was that the percentage of both radio and television audiences rose first and then decrease, while the total number of the latter was bigger than the former. In addition, the prime time for radio and television was 8 am and 8 pm, respectively.
