I am a big fan of the Software Wars graphic map.
Since it hasn’t been updated for years, MrTomLinux decided to recreate it from scratch in SVG
and to share the files. [I have forked it in github https://github.com/mariuz/software_wars_map]
http://blog.mrtomlinux.org/index.php?pages/Software-Wars You can open and edit the svg in Inkscape http://www.inkscape.org
You can follow the changelog :
Google brought Motorola
Nokia failed in the smartphone market
Mono and all it's team is departing Novell under Miguel leadership
