Last week, Facebook unveiled Deals, which many have billed as the social network’s Groupon killer.

At PR Daily’s LinkedIn group last week, many readers weighed in about the announcement. Georgia Cross, the director of marketing and brand development at Blue Cross MD, suggested Deals might hurt the Facebook brand.

“I think Facebook deals would be great for people who already ‘like’ a brand/ company page ... that would make them more relevant,” she said. “Otherwise, the company could get the reputation for being a deep discount brand, when their brand image was intended otherwise.”

Someone had better tell that to AT&T. On Tuesday, it unveiled its own Groupon competitor. Its Deal of the Day service will roll out soon in Atlanta, Dallas/Ft. Worth, and Los Angeles.

Before the market gets even more crowded, here’s an infographic from the website Online MBA comparing Groupon, LivingSocial, Facebook Deals, and Google Offers.
