In 1983 Apple created a job title that had belonged to churches. Guy Kawasaki became the software evangelist for the Macintosh.
His task was to convince developers to write for a computer with zero customers. Apple chose the word deliberately. The company viewed the Macintosh “as not merely another personal computer platform, but as good news.”
The title spread through the industry. “Chief evangelist” is now a standard role at technology companies.
