Insomniac Games was founded as Xtreme Software on February 28, 1994.
In 1995, Xtreme Software was renamed to Insomniac Games and debuted their first logo: a logo colored in red with the word "Insomniac' with an oversized "O" between the "S" and the "M" along with the word "Insomniac" outlined in the same color. This logo was first used on their first game, Disruptor.
While Ratchet & Clank is in development in 2002, Insomniac Games has introduced their second logo, which had replaced the oversized "O" into a moon resembling the letter "O". The last game that had used this logo is the 2016 reimagining game of Ratchet & Clank.
On September 20, 2017, Insomniac Games updated their logo by replacing the "O"-shaped moon on the word "Insomniac" with two crescents, which resembles the letter "O" just like the previous logo.
