National Public Radio combined computer code, archives and Google Hot Trends to create an automated Twitter account NPRBackstory. It goes like this: the code automatically detects frequent search terms, checks within the NPR archives for related stories and posts the link on Twitter, all without any human involvement. The goal of the project is to provide some backstory and context to breaking news, and to make full use of the online NPR archives that date back to 1995.
