Google implemented ARC for their partner sites, Advanced Rsomthing Cache, I believe. It was a way for google to consume popular websites and host them optimized for mobile (android) devices. It was all the rage for a while, because, I think, Google greatly favored ARC sites/pages for a while. Eventually they discontinued it, because, well Google.
