Cromemco's Dazzler (or TV DAZZLER) was a graphics card for S-100 bus computers. Released in 1976, it is the first commercial color bit-mapped graphics card available for microcomputers. Multiple Dazzler cards could be installed in a single machine and synced together, a feature which could, with minor modification, be used to genlock. Genlocked Dazzler cards drove ColorGraphics Weather Systems displays that generated most of the weather imagery seen on US television in the early 1980s. Excerpted from Wikipedia.
