Despite the launch of the PlayStation and Saturn, sales of 16-bit games and consoles continued to account for 64% of the video game market in 1995. Sega underestimated the continued popularity of the Genesis, and did not have the inventory to meet demand. Sega was able to capture 43% of the dollar share of the U.S. video game market and sell more than 2 million Genesis units in 1995, but Kalinske estimated that "we could have sold another 300,000 Genesis systems in the November/December timeframe." Nakayama's decision to focus on the Saturn over the Genesis, based on the systems' relative performance in Japan, has been cited as the major contributing factor in this miscalculation.
