What is inline skating?

Inline skating is the official term for the sport commonly known as 'rollerblading' or simply 'blading'.

Rollerblading is not actually a real term, and was derived from a company called Rollerblade.

Rollerblade didn't invent inline skating, but managed to promote the sport among a much wider audience. Rollerblade was the only company in the inline market for a long time and became the market leader.

This led to the generic use of the term 'rollerblade' for inline skating, similar to how Kleenex, Coke and Xerox have come to symbolise their markets.
