It is true that during certain period (IIRC, 2000 - 2005), before Stringer came aboard, the other division is losing money (electronics, Mobile, movie making), while only the game division get profit (don't confuse profit with revenue / sales). That is one of the reason Ken Kutaragi was "golden man" at SCE. However, PS3 and arrival of Stringer is the major turning point, in which all SCE division turn their situation around (game losing money, other divisions get profit).
