Skype may be American now, but it's origins are clearly European.

"Skype was founded in 2003 by Janus Friis from Denmark and Niklas Zennström from Sweden. The Skype software was developed by the Estonians Ahti Heinla, Priit Kasesalu, and Jaan Tallinn, together with Friis and Zennström were also behind the peer-to-peer file sharing software Kazaa. In August 2003, the first public beta version was released."

Until it was acquired by eBay, it was a Luxembourgish company. I don't know how a company could be more European in origin.
