Apple CEO Tim Cook still classifies the Apple TV set-top box as a “hobby.” Still, he says it’s a product he can’t live without.

“The Apple TV product is doing very well, and during the last fiscal year that ended last September, we sold a bit above 2.8 million units,” Cook says. “In the past quarter, we sold over 1.4 million Apple TVs, which is a record. We continue to add things to it.”
