Advent Corporation

Advent Corporation was a consumer audio and video hardware company founded in Cambridge, Massachusetts by Henry Kloss in 1967.

Citing high labor costs, it closed its Cambridge factory in 1979, laying off most of its 650 workers, and moved production to New Hampshire.

KVC ran into increasing competition from Japanese manufacturers entering the now-proven market for large-format consumer TVs, eventually selling its assets and shutting down.
