Fun facts
This format was an enhanced version of its predecessor, the failed M format; while the cassettes were similar, they used different magnetic tape formulas and signal processing methods
This format was developed to compete with Sony's Betacam SP format; while it gained some popularity, it largely lost out due to lack of reliable, affordable repair support
The M and MII formats, like the U in U-matic and the B in Beta, were named after the M-shape of the tape threading through a playback device (and VHS used this same technique)
