Just the fact that apple only sells 3 phones (2 old models) at a time while the other competition will sell dozens of new just shows how well apple is doing in the phone market.
with just one model! that's impressive.
The chart is not about number of models nor their current sales.
The chart shows the number of current
subscribers of a certain brand. That includes people using second or third hand phones. For example, even an iPhone 3G user counts.
Is this all phones or just smartphones?
If so pretty impressive considering Apple only makes smartphones.
It's for all phones in the US.
Btw, while 50% of US sales are now smartphones, I think actual smartphone subscriber base is still around 30%. So it's even more impressive.
Remember when the first iPhone was released, Jobs said he'd be happy with capturing just 1% of the smartphone market. And at that time, many analysts were predicting that it would be difficult for Apple to do even that. "It doesn't have a physical keyboard!"
The main reason why analysts didn't think the first iPhone would do well, was that it cost $500 for the 4GB model and $600 for the 8GB. US consumers weren't used to paying anywhere near that amount.
And they were right. Sure enough, sales slacked off quickly and Apple had to radically drop the price about two months later. Again, sales soon dropped. So Apple went with the usual subsidized price method for the next iPhone model, and sales took off.
