Bloomberg.com reports, “Domino’s Pizza Inc. (DPZ), the second- largest U.S. pizza chain, said digital orders are approaching 30 percent of all sales.

The digital orders include sales though the company’s website and smartphone applications, Chief Executive Officer J. Patrick Doyle said today during a conference call with analysts to discuss fiscal third-quarter earnings. The Ann Arbor, Michigan-based company will also expand the use of call centers to help with telephone orders in stores, he said.”

“Domino’s, which reported a 33 percent jump in third-quarter net income, has sought to boost U.S. sales with smartphone applications and a website that lets customers track their orders. The company in September said its apps for Apple Inc. (AAPL)’s iPhone and iPod Touch brought in sales of $1 million in a week.”
