I'm not saying the govt should regulate Zynga. I'm pointing out that they do regulate slot machines. That's because people know slot machines can be bad for people, and are generally a pointless waste of time and money that feel good in the short term. Clubs and pubs that operate those machines and know damn well that people misuse them resist these regulations to the last. The same attitude toward voluntarily stopping these things is being displayed here. And the TV thing was an accidental misstatement. I think the same thing is true to some degree or another of serialised TV and most MMO's. Serialised TV is all about making you want to see the next episode. MMO's are all about rewarding high play times rather than skill.
