Is it bad to be disruptive? The Oxford English Corpus would suggest it is， with violent， destructive， dangerous， and antisocial all commonly paired with the word. However， a new form of disruption is emerging - one that many people are welcoming and even encouraging. Disruptive behaviour may be the most common combination in the Corpus， but it is closely followed by disruptive technology, a concept first described in 1995. The new sense refers to innovations that improve products or services in an unexpected way， and thus disrupt the established market: a market ripe for breakout disruptive technologies ｜ disruptive innovations often see failure before success.
