Unlike M, MII was somewhat successful when it was first launched, with customers like NBC in the US and NHK in Japan using it for electronic news gathering (ENG), and PBS in the USA using it in the late 1980s to delay their television network programming by 3 hours on broadcast delay for later airing on the West Coast. But MII also suffered from lackluster marketing, a lack of customer support and public relations from Panasonic and Matsushita (Panasonic's parent company), and most importantly, a lack of reliability due to said lack of support for repair and service. This resulted in MII not being nearly as successful as Betacam SP. NBC eventually dropped the format in the early 1990s for Panasonic's D3 Format, and ultimately began broadcasting all of its television programming and television commercials from digital video servers in the 2000s.
