Google, Yahoo, Microsoft and MapReduce
1. MapReduce is a software framework invented by Google.
2. Hadoop is open source implementation of MapReduce, supported (in part) by Yahoo.
3. The most coherent description of MapReduce I read so far, could be found in the paper from Microsoft.

"Invented" is a little too much credit for something that has been around for decades.
