Much more than a decade, I'd wager! Ante stopped being standard quite a long time ago. Personally I stopped playing in 1997 and ante had already ceased to be a common practice in my area several years before that, from what I remember. Just googled it and the last card to even have an ante-impacting ability was printed in 1996. Seems it stuck around as an optional rule but wasn't common in my experience, probably because tournaments always skipped it.
