The Forgotten Tale of Cartrivision's 1972 VCR

harrymcc writes: In 1972 -- years before Betamax and VHS -- a Silicon Valley startup called Cartrivision started selling VCRs built into color TVs.

And it was a spectacular flop. Over at Fast Company, Ross Rubin tells the fascinating story of this ambitious failure.
