The information lifecycle refers to how information is produced and how it changes over time.
Why should you care about the information cycle?
If your topic is a current event, you might only be able to find first-person accounts (interviews or tweets), newspaper articles, or videos on news sites. If you need more in-depth expert analysis, it might be too soon for anything to be published. It takes time for the cycle to evolve and knowledge to develop!
The University of Illinois Library defines the information cycle as the progression of media coverage of a particular newsworthy event.
Take a look below at the library's great infographic on the information cycle. You can also view the text version.
