After 40 years, Sony will end production of BetaMax tapes in March.
"Sony introduced the consumer-friendly Betamax recorder, a suitcase-sized machine that recorded up to two hours of video on a cassette tape off of broadcast or cable signals, in 1975. And that ushered in era of the VCR. (That stands for video cassette recorder, millennials.)"

How about 2-inch quad [wikipedia.org]? A video of an Ampex VR-1200B VTR being loaded and played [youtube.com].
Or if you don't count 2-inch quad because you can't scrub forward and backward, there's 1-inch Type C videotape, also in reel-to-reel format [wikipedia.org]. Here's an Ampex VPR-3 VTR in action [youtube.com].
Also, you can still buy Betacam tapes from some places [google.com]. While Betamax faltered in the consumer market, Betacam was a staple in the ENG (Electronic News Gathering) market.
