51Degrees was founded in April 2010 when we released an open source version of an ASP.NET module to detect mobile devices and redirect initial requests from these devices to a mobile friendly home page optimized for the small screen. This project, now titled 51Degrees Foundation, is freely available on Codeplex.

The Foundation is being continually updated to support new mobile devices and features requested by developers. Our goal is to maintain a fully open source server-side multi device detection solution.

Why the name 51Degrees?

We're based in Reading, a UK town west of London. Reading's northern latitude is 51 degrees. As knowing a mobile devices location is such a major component of a great mobile user experience, we reckoned it was an appropriate name. How much more successful would a mobile web application be if it placed likely options relevant to the current location at the top of a list for easier selection, or avoided the use of a small and awkward keyboard to request an address or place name? It really is as simple as that!
