Here's a little light reading for your day. Actually, it's a lot of light reading: a six part retrospective detailing the history of Sega's involvement in the world of video games, all the way from the days of the SG-1000 to the company's implosion with the Sega Saturn and Dreamcast including looks at the Master System, Game Gear, Genesis, and the many add-ons and proposed extensions for those architectures. Go ahead and do the "SE-GA!" chant and/or scream as the articles load. You know you want to.
