The line chart presents the changes in global sales of movie tickets over a thirty-year period starting in 1980. Sales are divided by film type and are shown in millions. Overall, sales have increased during this span, with the exception of comedy films, which saw a slight decline.
Comedy films were top sellers with just over 600 million tickets sold in 1980 and steadily fell to around 350 million by 2000, roughly equal to horror film ticket sales. At this point, the genre saw a rebound and finished the period with about 500 million in sales by 2010.
All four of the other genres witnessed an increase in sales, with action/adventure and animation movies showing the greatest rises, especially after 2000. Action/adventure ticket sales almost quadrupled from just under 400 million to about 1.5 billion over the span of the graph, while animation films, which started at the same level as documentaries in 1980, grew 12 times, going from 100 million to 1.2 billion. Documentaries and horror films, though tripling and nearly doubling respectively, had a less significant rise.
