Long Tail - Wag the Head?

I agree that ‘Long Tail’ by Anderson is a compelling idea, which clearly shows how digital technology might be changing both markets and business models. It’s a ground breaking work on new business principles. However, I am also interested in Anita Elberse’s refutation that “the web may have actually increased attention to mainstream content, often referred to as the "head," while Anderson believes that consumers have used the internet to embrace niche content.” According to her, the continued dominance of big media and mainstream content has much to do with a human desire to experience culture communally. She argues, thus, that "the internet simply amplifies that drive." In this context, can we conclude that the (long) tail really is wagging the head with the advent of digitized era?
