After talking about the success of the Apple Store and the recent openings in China, Tim Cook talked Mac at today’s iPhone event.

He then moved on to how the iPod “revolutionized the industry.” He says the iPod has 78% of the portable music player market, compared to “other” at 22%. You may note that Microsoft has discontinued Zune.

Over 300 million iPods have been sold, Cook said, noting that in comparison, Sony sold 220,000 walkmans in 30 years.

Personally, I’d still credit the Walkman for paving the way for the iPod.

45 million iPods were sold from July of last year to this past June.

iTunes is up to 20 million songs, which is twenty times the size of when it launched, making it the nubbier one music store in the world with 16 billion songs downloaded.

Presumably, some iPhone stuff is still to come.
