The words "Telephoto" and "Zoom" were marketed heavily in the 1970s and 1980s. A 80-200 combines both words, thus making it very marketable. The ubiquity of these lenses is due to marketing. I can't say I don't own one, because 80-200mm lenses sometimes come free when you buy a body. Personally I don't find the combination (zoom + telephoto) very useful.
