Skype is a computer application that allows users to make voice calls over the internet free of charge. It was launched by three Estonian software developers in 2003 and has been one of the most popular online telephone applications, with an estimated 663 million registered users by the end of 2010.

"We wanted to introduce Estonia foremost as a smart e-solution country – small but innovative – which led to the logical idea to make a Skype phone booth," Merilin Pärli, communications coordinator at Enterprise Estonia told ETV.

Pärli recalled that Tallinn Airport is named after the former Estonian president Lennart Meri, who never missed a chance to say that the country must seek its personal trademark.

"And if Skype isn’t one, then what is?" asked Pärli, adding that hopefully in the future such phone booths will be found in airports across the world.
