The history of "w00t"

It comes in a variety of spellings offline and on. The most common, woot, whoot, and w00t are, for our purposes, variations of the same lexical item, especially since the aspirated aitch is growing less common in American English. The latter variant, w00t, has two zeroes in place of ohs, a common characteristic of words originating from online entertainment, especially in multiplayer games, where goofy and ironic l33tspeak sometimes prevails. Other online variations are w00+ and w007.

As is the case for most words, the most popular question about woot is "Where did it come from?" Unfortunately, its origins are disputed and, also like most words, it's impossible to say with any certainty what the true origins are...

After a couple of examples of "whoot" or "woot" as an onomatopoeic representation of video game sounds in news stories from 1982, the earliest clear-cut use of the word found so far is in the name of the Atlantic City, N.J., entertainment tabloid The Whoot! which shows up in 1988 as a sponsor of the ugliest bartender contest in Philadelphia...

After discussing (and dismissing) a number of possible origins, the writer concludes -

The most likely explanation, as is usually the case, is far simpler. Woot is, with some caveats, probably derived from and most likely popularized by the dance catch phrase of 1993, "whoot, there it is!" In clubs and on dance floors across the country, in half-time shows and in baseball stadiums, "whoot, there it is" and plain old "woot!" were shouted long and loud by millions. It was used by hype men at hip-hop shows, dancers and cheerleaders at ball games, DJs at discos, and probably by ball-callers at bingos...

If woot had any kind of real presence before the songs—as something other than the name of the publication from Atlantic City—it has not yet been found. As a clear-cut term of celebration or revelry, it simply did not show up in the trillions of words published before 1993 and currently archived online and in periodical databases.
