Philco Predicta Television Advert, 1958 (image via sueism1)
Hi! I'm rereading High Wizardry (actually my husband is reading it to me because he hadn't read it before and it's a nice thing to do together) and I have a very important question. What do gimbals have to do with televisions? We read the Wikipedia page, and googled a bunch of things, and can't figure it out. Please save us from endless research. Thanks!
