I read somewhere that Nintdendo first marketed the NES as a toy thus the "Entertainment System" moniker. They didn't want it labeled as a video game system since the Atari era was over and people where more interested in personal computers and toys than gaming systems. If it weren't for the NES with R.O.B. and the Zapper getting into stores via a Hasbro commission we might not have Nintendo games today. Had they launched with SMB I think they would have still made it, but the thinking at the time was that video games were a fad.
