The Satellaview (サテラビュー Saterabyū) is a satellite modem add-on for Nintendo's Super Famicom system that was released in Japan in 1995. The name Satellaview is a portmanteau of "Satellite" and "view," and the official abbreviation for the system is "BS-X". "BS" stands for Broadcast Satellite, a common name of one of the direct broadcast satellites in Japan,  and "X" represents the figurative "unknown" or "nameless." In other vernaculars, the X can stand for "transfer", thus "Broadcast Satellite Transfer."
The BS-X would be connected to the St.GIGA satellite station between 4:00-7:00 PM. During this time, a player could download and play games. The BS-X system broadcasted for 5 years, up until June 2000.
