Video & Audio & Image sharing

Video, audio and image services are channels through which information is communicated predominately through non textual means. Video and image hosting services refers to websites or software where users can distribute their video clips and/or pictures. Many services have options for private sharing and other publication options.

YouTube is a video hosting service. It was founded 2005 and bought by Google 18 months later. YouTube is one of the largest search engines in the world and only second to Google itself. YouTube statistics show that over 6 billion hours of video are watched each month on YouTube—that's almost an hour for every person on Earth. Although YouTube is often considered by most as a means for delivering entertainment and music videos, communicators should also consider how it can be used to advance food safety and risk communication.


Podcasting as an audio media channel was first conceived back in the early 2000’s. It was not until around 2004, when Internet speeds increased and mp3 players became popular, that podcasting grew in popularity. Now almost every TV show and radio station publishes podcasts to complement their traditional media channels. Video podcasts (short clips of video, usually part of a longer recording) have also become extremely popular online. Podcasting has also been picked up by some print media, e.g. newspapers, who supply their readers with spoken versions of their content.


Flickr is an image hosting service created in 2004 and acquired by Yahoo! in 2005. With the development of camera phones and blogging, photosharing applications have become increasingly popular. Today, online photo management services such as Flickr, allow photos to be shared within seconds of taking them. If you are interested to learn more about the The History of Flickr you can listen to this podcast in which Caterina Fake, co-founder of Flickr, is interviewed.
