The Information Cycle: Instantaneous

This Guide explains how a range of information sources become available over time, following a major event like the London Bombings on 7 July 2005

Information available immediately

This page includes examples of information sources which became available as soon as the London Bombings occurred. 

The increase in mobile phone use, many with built-in cameras, and electronic social networking tools, such as Facebook and Twitter, mean that more instantaneous information sources are produced than ever before.

Mobile phone images

Social Networking Tools

Facebook was still a small network for American Universities in 2005 and Twitter did not exist at all so there are no historical records from these sources for the London Bombings. 

If an event occurs today there are immediately Tweets and Facebook posts giving people's thoughts and feelings on the incident.  Although Facebook is fairly private and most posts can only be seen by 'friends', Twitter posts can be seen by everyone and the use of tagging makes it easier to find Tweets on a particular theme or event. 


The increase in Closed Circuit Television (CCTV) cameras, particularly in urban areas, means there may now be live coverage of an event and/or the areas around where an event took place.

This picture of Davinia Douglass, with a gauze surgical mask over her burnt face, was taken as she fled the 2005 London Edgware Road blast. 

This photo became an iconic image of the London Bombings. 

Photographs and videos can now be immediately disseminated using mobile technology.
