Posted April 8, 2011 by James Brightman
PlayStation Network has seen a ton of growth in recent years, and Sony was more than happy to talk about it on a PlayStation analyst day. Lazard Capital Markets' Colin Sebastian has noted that PSN is quickly becoming a more popular platform for the casual and social market, which should bode well for PS3 broadening its demographics.
"Online continues to ramp on PSN. The PSN currently has 75M registered accounts WW (half of which are in NA), with over 1.4B pieces of content downloaded since launch. PSN appears to be gaining traction tapping into the casual and social gaming market with titles such as Angry Birds which is the most downloaded game through the PSN (it was launched in January 2011). PSN is also seeing good success with freemium/microtransaction models," he said.
Sebastian noted that Sony's success in bringing more casuals to the PS3's online network could be key for the future growth of the platform. "We think this could be a significant move for PSN because it can allow casual game publishers, in addition to traditional game publishers, to leverage the PS3 as a gaming platform," he said, adding, "We were encouraged by the free-to-play demo of Sodium."
