MarketWatch: HSN, formerly known as the Home Shopping Network, is no longer the cable shopping channel you may initially think of, and, believe it or not, arcade games have played a role in the shift. On HSN.com, there’s an arcade-game section where you can play 30 different casual games, from poker to Sudoku. A study four years ago found HSN’s core female customers not only love to shop but love to play casual games. The result: 1.2 million users have registered to play the games.
