A rare look at Nintendo of America in 1990 was recently uploaded to YouTube by the channel 'btm0815ma'.
This "raw" footage was filmed at its headquarters in Redmond, Washington as part of a news report. Apart from a look at the assembly of NES, there's an interview where one guy says it's a fun place to work and even a look at the Nintendo Power Line.
"From June 1990, here is raw footage shot at the Nintendo of America headquarters facility in Redmond, Washington."
It's great to see this sort of history being shared online, and most certainly brings back some nostalgic feels.
