The P and S together make a great logo when put together and it is using the Gestalt principle of closure in it. Also for the PS4 part, each letter is done with one fluent motion to finish each letter.
The logo is made by Sony and is used for its PlayStation 4 console.

Thank you for highlighting this! I love the design of the PS4 logo and other branding because of it’s simplicity and interesting nature. I appreciate the interesting typeface used in the ‘PS4’; the thinness of the lines and rounded corners lead to a more modern, yet still inviting feel.
The logo itself is a little more complex and while not my favourite, I recognize its strengths, and why it has been the PlayStation logo for years.
