The Xbox Live service remains significantly more popular than Sony's PSN among console gamers in the US, Microsoft has said.
NPD, the North American entertainment and sales monitor, published a report in August which examined new trends in online gaming, and found that Xbox 360 was 48 per cent more popular among online gamers than PS3.
That data was originally only available to those who purchased NPD's online Gaming Report, but on Monday Microsoft freely publicised the data on the Xbox Live newswire.
"We're proud and humbled to be the top online gaming service - according to NPD's August 2013 Online Gaming report, close to 50 per cent more online console gamers use the Xbox 360 for playing online than the PlayStation 3."
In May, NPD published data which claimed that "the PC ranks as the top platform for online gaming with 68 percent reporting that they use a PC for online gaming".
The company also claimed that Xbox 360 had become North America's leading online console for three years in a row. It added: "PlayStation 3 and Wii are about even in terms of online gaming usage, with 30 per cent of online gamers saying they use the consoles for online gaming. The PS3 actually increased 10 percentage points from 2009."
Microsoft also left an appreciative message for the support shown by gamers.
"First, we want to thank you for choosing and for spending more time with us. In the last 12 months, we delivered more than 20 billion hours of gaming and entertainment on Xbox, over 17 per cent growth over the previous year.
"Xbox Live has always been about building an amazing community. When we first launched the service back in 2002, our vision was to create a premium online place where friends could come together to play games.
"With your support we've created the world's largest, most-active gaming and entertainment community and now, as we look ahead to the launch of Xbox One, we want to pause for a moment to celebrate our community and tell you about what we are doing to make it even better."
Microsoft has set an Xbox One release date of November 22 across the US and several nations in Europe.
