The high launch price of the PlayStation 3 was considered a major drag on its popularity. In July 2007, Sony announced a drop in the price of the console by $100. This measure only applied to the 60 GB models and was exclusive to the United States and Canada, where those models are no longer in production. On October 18, 2007, Sony announced a US$100 price drop for the 80 GB model and a new US$399 40 GB model to launch on November 2, 2007 with reduced features such as the removal of backward compatibility with PS2 games. Within weeks, Sony announced that sales of the 40 GB and 80 GB models by major retailers had increased 192%. In November 2008, Sony launched a 160 GB model, and on August 18, 2009, Sony announced the PS3 Slim. The PS3 slim sold 1 million in under a month. It was then announced that a 250GB slim model was to be released. It was released on September 1 (or 3 depending on country).
