It's a sad truth, but to go further, new things are brought to life by companies pushing correlation to known/old things. A company name, for example, that is known, pushes a new product. The new product must be cool, because you already know the company. In reverse, some unknown companies will try to push a product which looks like something that is similar to what they know. "Oh, this looks like an ipod, I guess Rikkitikkytinyhoe Co. is awesome!" Smart consumers won't see this, but most consumers aren't smart and open-minded enough to consider things they don't already know about. The young do, because they like exploring, but the ones with money, the old, often don't. Higher price = better quality is also burned into consumer's brains.
Thus, given the above, Linux will probably grow the fastest through known companies that push it. Google Linux, IBM Linux, HP Linux, etc, if they even choose to mention the name Linux (which they don't have to, they can just talk about themselves and their software and how awesome they are), and maybe even eventually Microsoft Linux, that will probably be how the majority of stupid consumers come to adopt Linux.
