Steve Jobs Writes a Letter
November 16, 1982
Steve Jobs writes a letter to McIntosh Labs asking for rights to use “Macintosh” as the brand name of Apple’s still-in-development computer. McIntosh Labs makes high-end stereo equipment, and while Jef Raskin, creator of the Macintosh project, intentionally spelled the name with a letter “a” to differentiate Apple’s computer from McIntosh’s audio products, Apple was denied a trademark because the name was phonetically identical. Since the Macintosh team had become attached to the name, Steve Jobs wrote the letter hoping to get permission or a licensing arrangement. Gordon Gow, president of McIntosh Labs visited Apple headquarters for a product demonstration after receiving the letter. However, McIntosh lawyers advised Gow to rejected the request. It wasn’t until March of 1983 that Apple secured a license for the name Macintosh. In 1986 Apple wholly acquired the trademark for an undisclosed “substantial” amount of money.
