Fifty five years ago, the voice of the Arabs or Sawt Al Arab radio was launched in Cairo, broadcasting the revolutionary ideology of Egypt's new leaders -- the Free Officers who had overthrown the monarchy.
Taking advantage of cheap transistor technology the Egyptian regime was able to get its message across the Arab World.
And by using a combination of emotional Arabist rhetoric and popular singers like Um Khalthoum, the voice of the Arabs emerged at a critical moment in the history of Arab unity.
