 ## Background
 
-The original source map format (v1) was created by Joseph Schorr for use by Closure Inspector to enable source level debugging of optimized JavaScript code (although the format itself is language agnostic).  However, as the size of the projects using the source maps expanded the verbosity of the format started to be become a problem. The v2 was created trading some simplicity and flexibility to reduce to overall size of the source map. Even with the changes made with the v2 version of the format, the source map file size was limiting its usefulness.  The v3 format is based on suggestions made by podivilov.
