The NYT opened up access to its entire archive via an API, a programming interface. It lets developers use NYT news and stuff in their own applications.
Why does this matter? Their archives are newspapers biggest assets (yes, more than their journalists. Sorry). Especially the big, old, authoritative ones. This article explains some of the importance of the development. Or try this. Monetising the archive will be a critical opportunity and challenge for the largest media groups, one that will stretch their business, technology and editorial departments. This side of the business – use of archive, syndication etc – is hard to grasp but critical to the future of the industry.
