PlanetWeb
From Sega Retro
PlanetWeb, Inc. was a California-based software company specialized in applications and development tools for embedded devices. They have developed both the Saturn and Dreamcast web browsers. They used to maintain a Dreamcast web portal (dreamcast.planetweb.com), which was closed after deciding that too few people were using it.
PlanetWeb was acquired on late 2009 by Monotype Imaging, and have discontinued support for Saturn and Dreamcast products.
