Sony can now officially give itself a high-five. The multinational media company sold 3.3 million more PlayStation 4 consoles between July and September, bringing its total PS4 sales to an impressive 13.5 million in just less than a year.

Usually, the summer months are somewhat slow for the gaming industry, but this time frame proved to be the second most successful quarter for the Japan-based brand. Sony also sold more than 800,000 seventh-generation PlayStation 3 devices during the same period.

PlayStation 4 sales were so high that Sony claimed it was the primary reason behind the company’s 7.2 percent revenue increase.

According to its latest earnings report from the second quarter ending Sept. 30, sales increased 74 percent from the previous year during the quarter beginning July 1. Sales to external customers also increased 97 percent from the previous year. Sony managed to lose $806 million during the quarter, less than what investors originally predicted.

Sony remains in the console lead, with its eighth-generation PlayStation 4 coming upon its one year anniversary. The console launched on Nov. 15, 2013, one week prior to Microsoft’s competing device the Xbox One. Microsoft hasn’t revealed any sales data during the past several months, but an earnings report from Ubisoft on Thursday confirmed that 32 percent of all Ubisoft games were sold on the PlayStation 4 platform.

As of August this year, Sony was at 10 million devices sold. Sony reportedly sold 1 million units within the first 24 hours of its launch, and it sold 2.1 million consoles internationally as of last December. One week later, the Microsoft launched the Xbox One in 13 countries on Nov. 22. Though Microsoft hasn’t reveled any Xbox One sales data, it’s estimated the around 5 million Xbox One units have been sold. On Nov. 2, the company will reduce the cost of the Xbox one to $350.
