The given bar chart illustrates the global revenue generated by four types of digital games console games, handheld games, online games, and mobile phone games from 2000 to 2006.
Overall, it is clear that total sales of digital games increased throughout the period, with handheld games consistently leading in revenue. While the sales of online and mobile games grew significantly after their introduction, the revenue from console games declined steadily.
In 2000, only handheld and console games were available. Handheld games generated approximately $12 billion in revenue, almost double the figure for console games, which earned around $6 billion. Over the next six years, handheld game sales rose steadily, peaking at around $18 billion in 2006, while console game revenue experienced a gradual decline, falling to approximately $3 billion by the end of the period.
Online games appeared in 2001 and began with relatively modest sales, under $2 billion. Mobile phone games entered the market in 2002 with a similar starting point. Despite their late introduction, both genres experienced consistent growth. By 2006, online game sales had risen sharply to $9 billion, while mobile phone games reached $6.5 billion, with both surpassing console games in global revenue.
