Makers and sellers of consumer-electronics devices have been releasing their earnings reports for the latest quarter. Here's a look at selected companies that report unit sales on phones, tablet computers and other devices. Some companies including Samsung Electronics Co. do not release data on unit sales.
— July 19: Microsoft Corp. says it shipped 1.1 million Xbox 360 consoles during the April-June period, down from 1.7 million a year earlier.
Nokia Corp. says sales of smartphones dropped 39 percent from a year ago to 10.2 million in the second quarter. The company blamed "strong momentum" of competing smartphones. All regions showed a decline except North America, where sales of the new Windows-based Lumia line offset declines in traditional Symbian devices. Sales of all cellphones fell 5 percent to 83.7 million.
— July 24: Apple Inc. says it sold 26 million iPhones, 28 percent more than a year ago. It also sold 17 million iPads, an 84 percent increase. But average selling prices for both products were down. Apple sold 4 million Macs, a 2 percent increase, and 6.8 million iPods, a 10 percent decline.
TomTom says it sold 1.7 million personal-navigation devices in North America, down from 2.1 million a year ago. In Europe, it sold 2.4 million, down from 2.8 million. TomTom says market share was relatively flat at 45 percent in Europe, but down to 19 percent from 23 percent in North America because of a GPS chip product issue.
AT&T Inc. says it activated 5.1 million smartphones in its latest quarter, down from 5.5 million in the same period a year ago. Much of the decline came because AT&T subscribers are holding on to their phones longer.
— July 25: Nintendo Co. says it sold 710,000 Wii units in the April-June quarter, down from 1.56 million a year ago. Nintendo is coming out with a successor, the Wii U, this year.
