Naughty Dog due to Uncharted 2
Rockstar Games by Grand Theft Auto III
Insomniac Games because of Ratchet & Clank: A Crack in Time
Infinity Ward thanks to Call of Duty 4: Modern Warfare
Ubisoft caused by Assassin's Creed II

What? Insomniac had a huge hit with spyro and they had a great rep due to it. 

Agree with Spyro being the game that made Imsomniac famous, it sold very well everywhere even in Japan
