Sony have been celebrating the past 10 years of the PlayStation Store which started back in 2006. They provided every user a special avatar to use for their profile:

“To recognize and acknowledge those who have been with PlayStation Network from the very beginning, members with accounts of 9.5 years or more will receive an exclusive PS4 avatar.” In the email sent out to those eligible, they say, “You received an exclusive avatar to use on your PS4 system. You can find it in your system settings under Profile.”

They’ve also listed some achievements they had along the way including 25.6 billion trophies have been earned.
