The 3DO Company lacked the resources to manufacture consoles, and instead licensed the hardware to other companies for manufacturing. Trip Hawkins recounted that they approached every electronics manufacturer, but that their chief targets were Sony and Panasonic, the two largest consumer electronics companies in the world. However, Sony had already begun development on their own console, the PlayStation, and ultimately decided to continue work on it rather than sign with 3DO. According to former Sega CEO Tom Kalinske The 3DO Company was engaged in very serious talks for Sega to become involved with the 3DO. However, it was passed on by Sega due to concerns over cost. Panasonic launched the 3DO with its FZ-1 model in 1993, though Goldstar and Sanyo would later manufacture the 3DO as well. Companies who obtained the hardware license but never actually sold 3DO units include Samsung, Toshiba, and AT&T, who went so far as to build prototype AT&T 3DO units and display them at the January 1994 Consumer Electronics Show.
