The iPhone drove the creation of the modern smartphone market. Before 2007, only businessmen carried Blackberries. Now pre-teens have smartphones. There's a really powerful image NBC posted comparing the Papal Conclave in 2005 and 2013[1] that tells the whole story. Similarly, the iPad is driving the tablet market.
And that's just 3 recent consumer-facing categories. The list goes on as you dig deeper or farther back. If you're using Chrome, guess who started Webkit?

Edit: I should have said, guess who popularized Webkit. We can debate semantics on whether forking KHTML to Webkit makes Apple the author of Webkit or not, but I think we can agree Apple popularized it.
