ELI5: Why did cheats die out in video games?

Up, Up, Down, Down, Left, Right, Left, Right, B, A, Start? I miss them....

A few things. 

**The internet** basically gave everyone access to all the cheats, which ruined the monopoly Prima guides and magazines had on revealing them, or getting them as a reward for finishing a level or getting a secret.

**Achievements**, like on Steam or XBL, had to mean everyone was on a level playing field.  Cheats would destroy the integrity of the achievement system.

**Online play** is virtually ubiquitous.  Few games don't require a connection to the internet where you can be compared to other players, fight other players, etc.  Cheats would make all of this useless.
