The 1/2-inch open real recorders that Oliver mentions ... first black-and-white, and later color, and some with hot roll Assemble and Insert editing were called EIAJ for Electronic Industry Association of Japan.
Early Sony models were not compatible with others, and that's when the EIAJ came together to standardize the 1-hour reel to reel format. A high-end black-and-white would run about $3,000 in 1972 dollars; a color one about $5,000. A nice, middle class house back in 1972 in the U.S. cost about $40,000.
Other quirky formats (like Panasonic's 8-track cartridge type of video cassette that held 30 minutes for which you would have to wait for the tape to spool back in before ejecting it) were cumbersome and not reliable.
These machines were primarily used in schools, banks (they made time-lapse versions to record security cameras and fit 24-hours on a 1-hour spool), and behold, PUBLIC ACCESS cable TV shows, though, of course, the output would have to be run through a bulky Time Base Corrector in order for the cable operator to send it down the mux pipe.
We have several Sony B/W and Color EIAJ reel-to-reels, and I've watched black and white footage I shot on a Porta-pak when I was around 9 years old. LOL.
They still work.
At NAB 2016, I met engineers who actually restore them to get playback out of thousandds of archived tapes, and figured out a way to output a DOC/TAPE RF signal (Drop Out Compensator) so you can feed that separately from the VIDEO OUT to a Time Base Corrector with DOC, to help cover drop outs.
