PS4 users broadcasting directly from their consoles make up 10 per cent of all streaming on Twitch TV.
The video game streaming service has seen a significant rise in users since the console's US debut on November 15, the firm has said.
"As testament to the growing appeal of live broadcasting video game content, the amount of broadcasters on Twitch has grown from around 600,000 in October to more than 700,000 in November," said Twitch's VP of marketing, Matthew DiPietro.
"In addition to more than 100K new broadcasters signing up since the launch of PlayStation 4, PS4 owners make up ten percent of all content on Twitch based on minutes broadcast," he added.
Twitch streaming is an integrated feature of the PS4, allowing users to stream gameplay footage to online viewers or watch others' streams all directly from their console.
Ustream, a similar service to Twitch, is also integrated into the console. Sony says that PS4 users have made around 800,000 broadcasts on Twitch and Ustream combined, totaling over 20 million minutes - or just over 333,000 hours - of streamed footage.
"Interest in streaming live gameplay has surpassed our wildest expectations," said Sony Computer Entertainment Worldwide Studios president, Shuhei Yoshida.
"We're very excited to see gamers embrace live streaming from their PS4 system and we look forward to seeing how PlayStation gamers advance social gaming in the coming years," added Yoshida.
Xbox One live streaming via Twitch suffered a last-minute delay from its planned launch-day deployment.
Microsoft has said it aims to deliver the functionality "during the first part of 2014".
