Given that the .EUS domain represents the Basque language and Basque culture on the Internet, most of the websites using .EUS can be expected to post content in Basque. On the whole, when analysing the percentage of domain names that have content in Basque in the main Internet TLDs, the .EUS domain clearly stands out as the TLD that uses Basque the most. The presence of Basque is prominent across the .EUS domains. In this case, the number of websites that have content in Basque is 84.4%. So the .EUS domain can be said to be operating as the digital “lungs” of the Basque language.
