Joe Hull started his career in audio in the early 1960s working as a retail salesman
in Cambridge, Massachusetts, at a time when some customers still needed
convincing that stereo really was better than mono. In 1970, he joined the legendary
Advent Corporation, where he worked for 8 years in a variety of sales and
marketing positions, concluding that what he liked best was writing about high-
technology products, such as the first cassette decks with Dolby B, for a lay audi-
ence. He’s been doing just that for Dolby Laboratories since 1978, with a few years’
hiatus out on his own as a freelance writer. Joe works and lives in San Francisco.
