What is the difference between in-line skating and “rollerblading”?
In-line skating is the official term for the sport commonly called “rollerblading” or simply “blading”. The commonly misused term of “rollerblading” is due to the company called Rollerblade. Rollerblade wasn’t the first to produce in-lines, but managed to popularize in-lines faster and farther than anyone previously (in the States anyway). Rollerblade was the only company in the in-line market for a long time, so they naturally became the market leader. This lead to the generic use of the term “rollerblade” to stand for all in-lines, even if made by different companies. (This is similar to the use of “kleenex”, “coke”, “xerox”, etc.).
