The bar graph illustrates global sales of four types of digital games – mobile phone, online, console, and handheld – between 2000 and 2006, measured in billions of dollars.
Overall, it is clear that sales of handheld games dominated throughout the period, while mobile and online games showed dramatic growth, and console games gradually declined.
In 2000, only handheld and console games were sold globally, with sales of around $12 billion and $6 billion respectively. Over the following years, handheld games maintained steady growth, reaching approximately $18 billion in 2006, whereas console games consistently fell to about $3 billion by the end of the period.
Sales of mobile phone games began in 2002 at roughly $2 billion and rose continuously to reach around $7 billion in 2006. Similarly, online games emerged slightly earlier, around 2001, and experienced the most rapid growth, climbing sharply to about $9 billion by 2006.
In summary, handheld games remained the best-selling category, while online and mobile games gained popularity, and console games lost market share over the seven-year period.
