Inspired by the Geovision Song Festival 2016 and my Wiwaxian contestant Sibyl, I've written wikipedia articles on two vaguely related things:
A global TV show called Popstar Factory with contestants competing to become popstars and various country editions. Feel free to add your own country's version of the show or let me know here and I'll add it myself! Also, I didn't write which country originated the show. Wiwaxia I feel is too small and insignificant a country to have started it - any other bigger and more culturally dominant countries with major TV production companies (that have wiki articles about them!) interested in being the originator in 2002?
An aid event called Concert for Commonia with aid going to displaced Commonians. Feel free to add singers and pop stars from your country to the list (and expand on the article if you want) or let me know here and I'll add it myself.
