I always wonder that 1999 was the "birth" of LTspice.
I personally discovered that LTspice is a SPICE program in
the summer 2001. I still believe that I was one of the early
adopters using it as a general SPICE program. Also the
discussions about LTspice started in 2001 in the usenet,
sci.electronics.design and sci.electronics.cad.
A trademark information search on "LTspice" yields:
First Use Anywhere: . .10/1/1999
First Use In Commerce: 10/1/1999
The Help about box shows a copyright back to 1998.
The earliest messages about SwitcherCAD III, SwitcherCAD3 or
LTspice that I could find were in June of 2001. Some trade
magazine articles about LTspice also came out in June 2001,
so LTspice must have been available in at least May 2001.
Perhaps it was quietly available in 2000. I might send Mike
a link to the LTwiki page and ask for his input (or perhaps
the question might be received more favorably coming from you).
Hello analogspiceman,
I have sent an email to Mike and asked him about comments and
corrections.
Thanks, Helmut. I went ahead and also sent him an email, but
your support is appreciated. ... What? He just now replied,
wrote that he's off to Australia, but answered with some
interesting tidbits (and will give a more complete answer when
he gets back.
"LTspice was released in Oct 1999 at a meeting of Linear
Technology's Field Application Engineers. They were then free
to give it to customers they met on a visit-by-visit basis."
