Consumer electronics retailer RadioShack has reported total net sales and operating revenues for the year ended December 31, 2010 up 4.6% to $4.47bn (£2.77bn), while net income increased 1.1% to $206m (£127.8m). The sales increase was driven by a 4.4% like-for-like sales increase in company-operated stores and kiosks, helped by increased sales in the Sprint and AT&T postpaid wireless business, increased sales of pre-paid wireless handsets and airtime, and increased sales of wireless accessories.
