Roy Greenslade presents this four-part documentary series on the freedom of the press.
Part two: Freedom of the internet
How do the motives of mainstream news websites compare with the agendas of blogs?
In this part of 'Press for Freedom', we talk to Iraqi blogger Salam Pax and others who have delivered on-the-ground viewpoints in regions where the government would have otherwise silenced them.
In Kuala Lumpur, we hear from the government-owned Bernama press, who also fund Nam News Network, supposedly the only unfiltered news wire in a non-aligned world.
