The result of VHS’s open system still enabled porn to show up on it sooner. And that helped more dudes want to drop $1-2k on a VCR.
Beta_cam_ did live on as a TV video format, I used one in high school and our local cable access still ran on betacam S in the late 90s.
It was the same sized tape as Betamax, but ran at a much higher speed for better quality (more info per inch of tape), they even switched to digital at some point, but I’d move on to MiniDV in college by then.
