Google acquires mainly technology and talent, or in some cases it would pay big bucks to acquire marketshare. There is not much technology behind group buying things. And none of the Groupon competitors have the marketshare Google wants. Thats why it makes more sense for Google to spend that billion dollars on advertising/promotion etc. to gain probably more marketshare than getting LivingSocial's 10% or whatever.
