The air bags where each cell was independently inflated and sealed[1] were recently invented (2002) and there are a lot of patents for it.[2][3][4] It took several iterations of ingenuity to figure it out because the previous sheet of air bags had one inlet to inflate all the airtubes. All the tubes were connected to each other like the tubes of a waterbed. Since I've been seeing those inflatable air bags for more than 5 years in shipments from Amazon, Newegg, etc., it looks like industry adoption has taken less than 10 years.
