As a hit-driven business, the great majority of the video game industry's software releases have been commercial disappointments. In the early 21st century, industry commentators made these general estimates: 10% of published games generated 90% of revenue; that around 3% of PC games and 15% of console games have global sales of more than 100,000 units per year, with even this level insufficient to make high-budget games profitable; and that about 20% of games make any profit. Within years after Steam relaxed limits on which games could be digitally distributed on its service, they reported that around 80% of games failed to reach $5000 in revenue in their first two weeks of sales.
