Rapid Product Growth

What causes a product to be introduced to a market then receive huge amounts of demand? For me I think of innovation, a new product that finds a niche in the market. At least that is an obvious way to look at it. But is there other considerations, ones that do not rely on a extremely creative unique idea. I think there are strategies for this.

One I came up with is better production. For  example you plan to introduce a brand competitor into the market. Lets say the already established product has some monopoly power in its market therefore they have upped the price and with no real competition they haven't been producing efficiently. When you introduce your product you make it considerably cheaper and of equal to or greater value. You can make it cheaper because unlike your competition you have figured out a less expensive way to make it. Then what happens you create ill-will for your competition's product and boom your product received rapid growth because you have just taken your competition's market from them.

The monopoly is an extreme example but I think the concept still stands if you can produce a product more efficiently then the competition and you introduce it to the market at a much lower price you should see rapid product growth.

Here are some examples of how a product grows:
