Apple has posted a record quarterly revenue of $20.34bn (£12.85bn), compared to $12.21bn (£7.71bn) a year ago, after selling more iPads, iPhones, and Macs than ever.

Profit in the fourth quarter of this year came in at $4.31bn (£2.72bn), compared to $2.53bn (£1.6bn) a year ago. International sales accounted for 57% of the quarter’s revenue. Retail revenue was $3.57bn (£2.25bn), up 75% from $2.04bn (£1.29bn) last year.

Apple CEO Steve Jobs said: “iPhone sales of 14.1 million were up 91% year-over-year, handily beating the 12.1 million phones [Blackberries] RIM sold in their most recent quarter. We still have a few surprises left for the remainder of this calendar year.”

The technology giant also sold 4.19 million iPads during the quarter, compared to 3 million in the last quarter when it launched. Apple sold 3.89 million Macs during the quarter, a 27% increase.

Apple’s CFO Peter Oppenheimer said: “Looking ahead to the first fiscal quarter of 2011, we expect revenue of about $23bn.”
