About O'Reilly Media

O'Reilly Media spreads the knowledge of innovators through its books, online services, magazines, research, and conferences. Since 1978, O'Reilly has been a chronicler and catalyst of leading-edge development, homing in on the technology trends that really matter and galvanizing their adoption by amplifying "faint signals" from the alpha geeks who are creating the future. An active participant in the technology community, the company has a long history of advocacy, meme-making, and evangelism.

Publisher of the iconic "animal books" for software developers, creator of the first commercial website (GNN), organizer of the summit meeting that gave the open source software movement its name, and prime instigator of the DIY revolution through its Make magazine, O'Reilly continues to concoct new ways to connect people with the information they need. O'Reilly conferences and summits bring alpha geeks and forward-thinking business leaders together to shape the revolutionary ideas that spark new industries. Long the information source of choice for technologists, the company now also delivers the knowledge of expert early adopters to everyday computer users. Whether it's delivered in print, online, or in person, everything O'Reilly produces reflects the company's unshakeable belief in the power of information to spur innovation.
