Recently the US Olympics Committee sent a letter to Casey of Ravelry to cease & desist using the word, Ravelympics, as they own the trademark to any part of the word Olympics and can enforce the trademark as it's clear that Ravelry is using their site name + Olympics to create Ravelympics. To read more about it and read the actual letter, please visit Gawker and read their article: Knitters Outraged After US Olympics Committee Squashes Knitting Olympics - and Disses Knitters.
Dear US Olympics Committee:
While I understand that Ravelry should respect trademark and change the name of the Ravelympics to something else, I do not like the assertion that knitters coming together from all over the world to participate in friendly competition, while promoting the Olympics is somehow disrespectful to athletes. And the notion that knitters from all over the world, coming together for events, could not possibly promote education, culture, respect, world peace, and harmony as the Olympics do is just absurd. Wherever global tragedy strikes, knitters are lending a helping hand with hand knit toys, blankets, hats, mittens, scarves, prayer shawls, and the like. They sell patterns on Ravelry to benefit victims of global atrocities and natural disasters or to bring light to illnesses. They come from such varied backgrounds on Ravelry and use knitting as a way of connecting our cultures. Shame on you, US Olympics Committee, for writing a letter that could've merely stuck to the trademark infringement issue, but chose to insult millions of men and women for whom knitting is not a frivolous distraction, but a way to create, connect with others, and give back.
