I still find myself wondering if we aren't in an advertising bubble instead, with social media a rider and not a driver per se of the trend. I'd go a step beyond that and say if there is any bubble, it is based on a large number of people targeting market share of a market with a fairly constant size, advertising spend. Everytime you add a company trying to get advertising dollars, those dollars have to come from some other company and making advertising more efficient doesn't nessisarily mean Cheif Marketing Officers will increase marketing spend.
