Ztohoven (from 2003) is a Czech artistic collective known for its ironic, punning interventions, public actions and provocations dealing with media manipulations and the “hacking” of mainstream communication systems. Name Ztohoven can be read as Z toho ven (the way out), or Sto Hoven (the hundred shits). The core of the collective consists of Roman Týc, Aleš Kodim, Eman Cipace, Zdeněk Dostál, Míra Svoboda, Otto Horší, Tomáš Jasný, Dan Gerous, Anna Bolická, Tomáš Mrnc and Petr Žílka. The number of associates varies up as many as 100, according to the nature of the project. The group’s subversive actions have resulted in numerous arrests and multiple court prosecutions. Their actions include placing a question mark over Prague Castle, replacing all of Prague’s subway posters with question mark posters signed with the group's website, sending SMS text messages directly to the President of the Czech Republic, deputies, journalists and government members on behalf of the deputies themselves, and hacking a Czech Television live broadcast into which they inserted images of a nuclear explosion. The Czech National Gallery awarded the collective with the 2007 national prize for young artists.
