&gt;If manufacturers are introducing fewer models, it&#x27;s because there is reduced demand for them.<p>That assumes manufacturers solely pay attention to demand before making and selling a device. Which is wrong. They pay attention to what carriers want. Which is usually what will help them sell expensive data plans. Also, companies care about what Samsung is selling. In Samsung&#x27;s case they care about what components they themselves supply to other companies (SoC&#x27;s, OLED&#x27;s etc.). So it&#x27;s in their best interest to keep them in demand.
