While PSN has only existed 40% of the time Xbox Live has, it's only pulled in 20% of the revenue. Sony has raked in $180 million, as of E3 '08 Microsoft has pulled over $1 billion.
To Sony's credit PSN offers a free online multiplayer service which they hoped would prove a more attractive prospect against their rival’s subscription-based model. For now though it's Microsoft who get the last laugh as they enjoy the cost of their Xbox Live network paid for by the users.
"Sony has generated $180 million in gross revenue from PSN two-plus years of life. As of the last E3, after about five and a half years, Xbox Live had generated over $1 billion," reports .
From February figures last year around 56% of the Xbox Live worldwide user base were paying Gold subscribers. Sony announced recently that PSN beats Xbox Live's member count as they've reached 20 million users. Should Sony have charged for PSN?
