Around 200 Egyptian television presenters and producers on Sunday afternoon marched to Tahrir Square from state broadcasting headquarters in Cairo's nearby Maspero district to protest what they perceive as Islamist attempts to "dominate" state media.
Protesters marched around the square chanting "Free presenters say the media will be free" and "Free media is the property of the people." Marchers planned to return to Maspero Sunday evening to continue their demonstration.
Sunday's protest came in response to a sit-in staged since Friday by hundreds of supporters of Egyptian President Mohamed Morsi outside Media City in Cairo's 6 October district to demand the "purge" of Egyptian media from what they describe as elements still loyal to the ousted Mubarak regime.
The Egyptian Radio and Television Union is currently under the custodianship of Information Minister Salah Abdel-Maksoud, a member of the Muslim Brotherhood.
Maspero presenters and producers have staged several protests since last year's Tahrir Square uprising to defend the freedom of public media, which was closely controlled by the state during the Mubarak era.
Head of Egypt's state broadcaster, Essam El-Amir, resigned on Thursday to protest Morsi's controversial 22 November constitutional declaration. El-Amir tendered his resignation following Wednesday's clashes between supporters and opponents of the president, which left six dead and 450 injured, according to health ministry figures.
