Re: Changing directions
why they got failed?
Gigi3, there are multiple factors. One is traction or market share. If the market is dominated by good options, it is very hard to break in with a new option. It has to be vastly superior to the "good" choices already available and in people's hands.
Another factor is the ecosystem. Quite simply, there are a huge number of apps for both Apple and Android platforms. If you come to the market with another OS that requires it's own apps, you need apps. Which means that you need developers to adopt your system and build the apps.
A third key factor comes down to basic marketing and advertising. Entrenched brands have an edge. In the USA, for example, a large part of the population refer to all bandages as "Band-Aids," which is a name brand. The same applies to Kleenex and even Coke to refer to any carbonated drink with a carmelized color.
Those are huge market factors to overcome to break out a new product. It is possible, but not likely. It is also very expensive and relies a lot of other parties, like developers, over whom Blackberry has limited influence.
