A "long read" by Jason Burke, who has written several books on terrorism, the full title and sub-title being:
How the changing media is changing terrorism; Just like news organisations, terrorists need an audience – and both have adapted their tactics to keep your attention

These two passages explain much of his article:
The new wave of violent propaganda has prompted much debate about the role of Isis videos in attracting militants, as well as the degree to which the media itself is responsible for providing terrorism with the “oxygen of publicity”.

But certain crucial elements have received less attention. One is the way in which new technology has shaped both the media itself and terrorist organisations in ways which are strikingly similar. A second is the role we may be playing – albeit unthinkingly and against our better intentions – in the evolution of the media strategies of the very groups we so abhor. Neither of these possibilities is particularly comfortable to contemplate.
