Over the weekend, PSN members were sent an email from Sony regarding the renaming of PlayStation Network (PSN) Accounts. From February 8th 2012, your PSN Account will be known as Sony Entertainment Network Account or SEN Account for short.
This change will take effect at the same time as upcoming PlayStation 3 and PlayStation Vita system software updates. It appears that the PSP is unaffected.
According to the email, this transition is based on “Sony’s goal to enhance its unique digital entertainment offering.” The email goes on to state:
As a series of these activities Sony started last September, PlayStation®Network will be aligned with “Sony Entertainment Network”. This helps us get closer to our goal of establishing a global comprehensive network platform of services across games, movies, music and more, all accessible from one convenient account.
Your Sony Entertainment Network account also enables use of Sony’s non-game services such as Music Unlimited, Video Store of PlayStation®Store and PlayMemories Online (previously called Personal Space) across a variety of network-connected devices.
