When did DAS start getting so much press?

I feel like it's raining news about distributed antenna systems. First, the news that the passage of the Middle Class Tax Relief and Job Creation Act of 2012 is good for the wireless industry in general because it streamlines collocation on and modification of an existing structure that does not substantially change the physical dimensions of the structure. This measure will increase capital investment, spur job creation and accelerate the advance of all wireless networks. Then, SBA announced plans to buy some DAS assets from Mobilitie and TE Connectivity is teaming with ip.access for an integrated small cell and DAS.
