Did you know?

When the computer terms "software" and "hardware" sprang to life in the mid-20th century, a surge of visions and inventions using the new technology immediately followed . . . along with a revival of the combining form "ware." An early coinage was "wetware," which began circuiting techie circles in the 1970s as a name for the software installed by Mother Nature (a.k.a. the brain). Other "ware" names for people and their noggins have made a blip in our language - for example, "meatware" and "liveware" - but none have become firmly established in the general lexicon like "wetware."
