Philip Seib says the network helped Qataris "put their country on the map". Members of the audience nod ­furiously. Seib then points out how Al Jazeera was a "public diplomacy creation . . . probably one of the most successful in history". The Al Jazeera representative on the panel suddenly looks distinctly uncomfortable.

The political gamble has paid off as Qatar, perhaps the richest country in the world, emerges as a player able to deploy more than the soft power of TV channel Al Jazeera, which has fanned most of the region’s revolutions.

Al Jazeera’s rise has coincided with a decline at the BBC. Following a reduction in its Foreign Office grant, the corporation is cutting its World Service by 16 per cent, which will reportedly save £46 million a year. Al Jazeera is one of a number of foreign broadcasters lining up to fill the information gap that this leaves behind.

"Long live Al Jazeera!" chanted Egyptian protesters in Tahrir Square on Feb. 6. Many Arabs -- not least the staff at Al Jazeera -- have said for years that the Arab satellite network would help bring about a popular revolution in the Middle East. Now, after 15 years of broadcasting, it appears the prediction has come true.
