This line of thinking might have some merit.
But LG being the first one out with a 3D phone, dual core phone, first OLED tv is not a marketing thing. Neither is Samsungs dominance with the Galaxy line or its HDTVS when they popped up. Whats happened to Panasonic, Sanyo etc? Have they moved into other stuff (like Philips that has moved into medical appliences).
