Found this, which I'd never seen before, on the story behind Snowie:

http://www.snowiegroup.com/cartoon/

"The name Snowie originally came from SnowWhite. The first beta version that
played on the backgammon server fibs was named that way. Since the
architecture of neural network consisted of seven different neural networks
we came to the idea to call it after the story of SnowWhite and the seven
dwarfs. There is a main decision algorithm that decides which neural network
should be used in which situation. For obvious copyright reasons we then
decided to call it "Snowie"."

(...)

"In 1998 Snowie 1 came to the market. Snowie 2 followed half a year later
with a substantial improvement in its user interface. Early 2000 came Snowie
3 with a big improvement which were the live cube equities. These allowed to
measure error rates more accurately and also allowed a significant
improvement in playing strength. The neural network for the first three
versions was the same. The big step forward came in October 2002 with Snowie
4. This new neural network took more than 2 years of development and
training time and is a significant improvement. We believe that Snowie 4 is
the strongest player in the world."
