S3 is the only reason we can use textures in a usefull way ( S3 TC compression is their algorithm ) so I wouldn't say that they haven't been a company the last 10 years ;)
I know. It was introduced in the S3 Virge series of chips. The same one that (amoungst other things) powered the graphics card in my Amiga. Ten years ago.They also made (at least parts of) the FireGL card that used to be in my IBM IntelliStation, roughly 7 years ago, around the time they where acquired by ATi and Via respectively. So okay, maybe it was only in the last 5 years, but still...
