Carl Williams writes, "Tetris is the title that probably single handedly handed Nintendo the portable market in the late 80’s. This was accomplished via some shrewd business maneuvering with the right people on both sides of the table. It was also the pack-in title (remember those?) for the newly released Nintendo Game Boy. This single move is what probably handed Nintendo the fledgling hand held market. It certainly solidified Nintendo’s stranglehold over the market for decades to come. In the independent gaming world though, a company named Elektronite has been working to bring an official version of the block falling game to the Mattel Intellivision. They are not giving up."
