As you may or may not know, this year is Macromedia's 10th birthday. In celebration, i did a quick search to see what information i could find on the history of Macromedia and Flash. Here is what i found:

• Macromedia Survives a Decade by Reinventing itself [via JD on MX]
  
• The History of Flash (written by the creator of Flash)
  
• The History of Flash (slightly older version)
  
• Macromedia Timeline
  
• Flash Tutorial for Beginners (has brief history outline)
  
• The development of Flash (in Dutch, has screenshots of all versions) [thanks waldo]
  
• The Flash History (flashmagazine) [thanks jarle]
  
• Web Archives (futurewave) | (macromedia)

I also thought that Flash developers might be interesting in seeing some pictures of Macromedia headquarters, the Flash Team offices, and some of the members of the Flash Team.
