When it comes to pizza, everyone has an opinion.
Some of us think that our current pizza is just fine the way it is. Others have a favorite pizza joint that makes it like no one else. And many pizza lovers in America agreed up until recently that Domino’s home-delivered pizza was among the worst. The home-delivery market for pizza chains in the United States is approximately $15 billion per year.
Domino’s, which owns the largest home-delivery market share of any U.S. pizza chain, is finding ways to innovate by overhauling its in-store transaction processing systems and by providing other useful services to customers, such as its Pizza Tracker. And more important, Domino’s is trying very hard to overcome its reputation for poor quality by radically improving ingredients and freshness. Critics believe the company significantly improved the quality of its pizza and customer service in 2010.
Domino’s was founded in 1960 by Tom Monaghan and his brother James when they purchased a single pizza store in Ypsilanti, Michigan. The company slowly began to grow, and by 1978, Domino’s had 200 stores. Today, the company is headquartered in Ann Arbor, Michigan, and operates almost 9,000 stores located in all 50 U.S. states and across the world in 60 international markets. In 2009, Domino’s had $1.5 billion in sales and earned $80 million in profit.
