CBS and Fox News have very similar multimedia options offered on their webpages. Both are active on Twitter and Facebook, and offer radio, podcasts, and video of their content. CBS also has a YouTube page that viewers can follow, if they so desire.
The multimedia outlets, Twitter and Facebook, compliment news stories by providing a means for the corporations to get the main aspects of the news out to the general pubic. They allow for a short, informative synopsis of the news to be presented, which will hopefully draw the viewer to their site in a quest for the more detailed information. The video options highlight the main aspects of a story and put a identifying face to the person or location that the news is referring to, if any.
The writing accompanied along with these multimedia options is short and accurate. It is a lot of information compressed into a small space. The point of a tweet or Facebook status is to inform/update the reader on the news without bogging him/her down with the less critical information.
