More than three million dot-eu domain names have been registered since the establishment of the Internet domain less than three years ago.
According to EURid, the European registry for dot-eu, the three millionth domain name was registered on January 11th by a German resident.
In 2008, more than 274,000 dot-eu domain names were registered, with Poland seeing the healthiest growth at 69,000.
Supporters are hailing the milestone as an endorsement of the domain.
"The three million dot-eu domains reflect the confidence of European Internet users in sot-eu," said Viviane Reding, EU commissioner for Information Society and Media.
"This achievement, just a few months before its third anniversary, indicates how dot-eu has clearly won
public favour: a growing number of Internet users are embracing the opportunity to express their European character online."
Marc Van Wesemael, general manager of EURid, said using the domain was a "sound business investment".
"The free flow of trade within the European Union and the growth of online commerce have created enormous opportunities in this market," he said.
