Despite being big winter sports fans, and consistent medal winners in the past, Czechs were reluctant to attend the 2014 Winter Olympics. Visas, inflated costs and a complex history with Russia meant that the Czech team would be left with precious little support on the ground in Sochi. Czech Radio, the official media sponsor of the Olympic team, created a smartphone app which depicted an exact replica of the night sky above Sochi, with real stars that fans could tag with messages of support for their heros. The Czech athletes could then read, like and respond to the messages through special personalized versions of the app.
