Terrorism, global reactions, the media and their general position in society

In July 2011 when the Norwegian tragedy took place, the news was  lettered with items related to the tragedy, however, did you notice a weird thing there? The word terrorist or terrorism didn’t seem to be mentioned as much when describing the act or the person causing it!
This is particularly surprising, knowing how the media usually portray these type of incidents and how they love to sensationalise and dramatise news. Weirder still, a few weeks later and outside of Norway, you will barely hear about the issue any more!

A question that would pop in my head here is would this have been different if news agencies managed to find an Islamic link anywhere?
