"Groupon and Deutsche Telekom Forge Alliance" "Moving past revenues, the Groupon deal also puts Deutsche Telekom squarely in the middle of a mobile advertising boom that looks likely to explode in Europe soon with a very credible offer. Deutsche Telekom competitor, Telefonica of Spain recently said that some 23% of its user base in the U.K. opted into its O2 More mobile marketing and advertising service, which sends company offers and information via email and text based on user interests. Google bought DailyDeal, a deals website in Berlin, in September reportedly for $150 million. Last year, Nokia, which also sells a good number of phones in Europe, folded its Navteq mapping unit into the company to create a new division and take aim at location based advertising."
