Read-Only Memory is a British publisher of art books on topics of video game history and culture. Following a resurgence of interest in 1980s and '90s British video game development, the company crowdfunded and produced four art books: an oral history of that Britsoft era, two books on British developers Sensible Software and The Bitmap Brothers, and a definitive volume on the Sega Mega Drive/Genesis, for which the publisher became best known. Read-Only Memory's books are archival anthologies, including original design documents juxtaposed with developer interviews and high-quality prints of in-game graphics. Reviewers were particularly impressed with each book's breadth of unreleased concepts.
