Just two months ago, BIA/Kelsey predicted that the U.S. daily deals market would grow from $1.25 billion this year to $3.93 billion in 2015, and while an increasing number of companies are entering this market, AT&T has announced that it wants a piece of the pie as well. 

AT&T's daily deals service will be available on its yellowpages.com subsidiary, and will initially be available in Atlanta, Los Angeles and Dallas-Forth Worth. 

AT&T did not say which businesses will be apart of the new service initially, but did mention that consumers who register starting today will receive a $10 credit. But the service does not officially launch until next month. 

Groupon, a deal-of-the-day website with over 35 million users that launched in November 2008, has been the leader of the daily deals market with more than 150 markets in North America and 100 markets in Asia, Europe, and South America. 

After dominating this market for years, Groupon now has some competition as other companies step in for a cut. For instance, Google launched a marketing daily deals service called "Offers" two weeks ago in Portland, Oregon, and Amazon invested $175 million into LivingSocial last December, which is a social commerce company. In addition, Facebook just introduced "Facebook Deals," which allows users to purchase coupons for social events right off of Facebook.
