Rollerblae is a type of inline skate. The name is a registered trademark owned by Nordica, part of the Tecnica Group of Trevignano, Treviso, Italy. Scott and Brennan Olson sold their Minneapolis company and it became Rollerblade, Inc. which has changed hands over time between Nordica, Benetton Group and Tecnica. The Rollerblade trademark has been in use since March of 1983. While the company does not want the meaning of its trademark to be diluted, the term "rollerblade" is frequently used in casual conversations as a generic word for any inline skate, regardless of brand. This misuse has also appeared on "official" items such as signs, buildings, and sidewalks.
