The government simulation browser game NationStates, which allows players to decide the political leaning of their countries, featured until 2008 a virtual United Nations body where player nations could approve global legislation. The in-game United Nations rebranded as World Assembly after the United Nations sent a cease and desist notification to the game's creator.
Speaking of cease and desist, The punk band United Nations, which formed in 2005, received several cease and desist letters from the United Nations organization and was sued for using the same name. While the lawsuit did not achieve its goals, the band's Facebook page was shut down, the band's publicist resigned, and the band's label stopped printing the band's first album. The band later released a second album, featuring the organization's cease and desist letters on its cover.
