my memory isn't that great especially because internet products dramatically changed. i am guessing, some recollection of them, that beta versions of vivoactive producer were available probably from 1994 to 1995, until the first commercial version of VivoActive Producer was produced. They could have been produced earlier but i don't believe so.
vivo software inc, organized in 1992, was the owner of
www.vivo.com until vivo's purchase in 1998 by realnetworks.
