No matter what kind of industries or what kind of products, there is always a life cycle of a market. when most persons think only technology-break-thru idea could make a buesinss flying, that is not true. In fact, a business can be successful or not depends on how good it can realize the stage of the life cycle and put itself on right position. For example, tissue paper market is a mature industry therefore Kleenex spends lots of marketing fee on doing advertisement and they are still making good profit. However if someones want to build a start-up from garage w/o rich family, a disruptive idea should be the only way to do.When Jack Welch took CEO role at GE, he realized most of GE's products are on declining period, What he focused was to restructure GE. Only profitable and on great postion on market were kept, others all gone. That shows no matter where you are on the chart, as long as you can realize and play great role, you have your chance.
