Microsoft's fiscal third-quarter profit declined 6.5% dragged down by slumping PC sales. The e-commerce giant, which is also rapidly expanding its lineup of devices and computing services, reported earnings per share of 23 cents.

The company's revenue rose to $19.74 billion. Net sales increased 23% to $19.74 billion in the first quarter, compared with $16.07 billion in first quarter 2013.

Amazon's international unit, which accounts for 40 percent of sales, continued to be a drag as sales growth slowed to 18 percent during the quarter. Global unit sales also decelerated, rising only 23 percent.

"We get our energy from inventing on behalf of customers, and 2014 is off to a kinetic start," said Jeff Bezos, founder and CEO of Amazon.com. "Our device team launched Fire TV, offering great content, including our recently announced exclusive deal with HBO, and innovative features like unified voice search, which we?re delighted is being adopted by so many new partners, including Netflix, HBO Go, Hulu Plus, Crackle and Showtime Anytime. The team is working hard to keep Fire TV in stock. Our retail team launched Prime Pantry, a new option available only to Prime members offering exclusive access to everyday essentials in non-bulk sizes ? ranging from breakfast foods and popular soft drinks, to cleaning and personal care items. And, our AWS team significantly lowered prices on EC2, S3 and RDS, saving AWS customers hundreds of millions of dollars over the next several months alone."
