In 1991, the SNES-CD was to be announced at the June CES. However, when Hiroshi Yamauchi read the original 1988 contract between Sony and Nintendo, he was furious. He deemed the contract totally unacceptable, and secretly cancelled all plans for a joint Nintendo-Sony SNES CD attachment. Indeed, instead of announcing their partnership, at 9 am the day of the CES, Nintendo chairman Howard Lincoln stepped onto the stage and revealed that they were now allied with Philips, and were planning on abandoning all the previous work Nintendo and Sony had accomplished. Lincoln and Minoru Arakawa had (unbeknownst to Sony) flown to Philips headquarters in Europe and formed an alliance of a decidedly different natureโone that would give Nintendo total control over its licenses on Philips machines.
