Apple sold more iPhones and iPads in the fourth quarter of 2013 than during any other three-month period, the company revealed late Monday afternoon. Specifically, the Cupertino-based electronics maker shipped 51 million iPhones, 26 million iPads and 4.8 million Macs en route to record quarterly revenue of $57.6 billion and quarterly net profit of $13.1 billion.

For reference, Apple sold 47.8 million iPhones, 22.9 million iPads and 4.1 million Macs during the year-ago quarter. But despite settings records across the board, iPhone sales fell short of industry expectations. Similarly, profits remained flat at $13.1 billion compared to last year's figures which sent shares plummeting by more than eight percent in after-hours trading.

Apple entered the holiday buying season with a bevy of new products including the iPhone 5s and the iPhone 5c as well as the iPad Air and second generation iPad mini - all of which arrived in plenty of time for holiday shoppers.

CEO Tim Cook didn't give a breakdown of sales figures for each new iPhone model but he did say that demand for the iPhone 5c turned out to be different than they anticipated. He believes people were intrigued by Touch ID and combined with other things unique to the 5s, it earned a significant amount more attention and a higher mix of sales.

If you recall, Apple signed a long-awaited deal with China Mobile for the iPhone but those sales figures weren't included in the latest earnings report. That's because the handset didn't go on sale in that region until January 17 so we'll have to wait until next quarter for those results.
