Change in market- Console game to Smart phone game

We used to play a lot of console game by using television. But now days, many people don’t use television and console to play game. This is because the substitute for console games has placed. The substitute is called smart phone games. When smart phone has released, Sony, Nintendo and X-box didn’t expect that this will treat the console market, but the popularization of smart phone brought many derivative markets, such as application. And one of the derivative is the smart phone game market which threats the existing console market.

The popularization decreases the market share of console game and increases the smart phone market share. This shows me that how things are connected and how fast businesses change. Also every business has potential threat that should be always managed and observed.
