The AP is launching an all out assault on any use of its content that is not licensed (purchased) for use by Internet publishers and search engines. As I have said in the past, the AP is not just focusing on the blatant violators such as spam blogs or sites that quote paragraphs without attribution or link. On the contrary, the AP is specifically going after bigger mainstream blogs, Internet publications and believe it or not search engines such as Google.
