 and 

social networks

. The growth of social networks has been documented by 

Boyd and Ellison (2007) who describe social networking sites as:

 Web‑  based services that allow individuals to (1) construct a public or  semi‑  public  profile 

within a bounded system, (2) articulate a list of other users with whom they share a con‑

nection, and (3) view and traverse their list of connections and those made by others 

within the system.

The interactive capabilities to post comments or other content and rate content are surpris-

ingly missing from this definition.

Podcasts

Individuals and 

organisations post online 

media (audio and video) 

which can be viewed in 

the appropriate players 

(including the iPod which 

first sparked the growth in 

this technique). The latest 

podcast updates can be 

automatically delivered by 

really simple syndication.
