Getting Game Cheats for PS3

Since the PS3 is still kind of a new system it seems harder to get game cheats for PS3 games. I remember when the business of game cheats was a booming business back when the Nintendo still ruled the world of home video games. Now days you can't buy books like you use to for simple game 1-ups. I'm guessing since the internet became a popular medium to search for game cheats; in effect all real authors of game cheats actual game cheats lost money and were unable to write online for the same money.
