Discussions about news media in America often focus on two main issues. The first is whether the news is influenced by one person or family who owns a controlling interest in the media company.
The second is whether the personalities who deliver the news also influence it. People like Brian Williams, Rush Limbaugh and Oprah Winfrey are believed to be able to express their opinions on facts and events. While this may be true, their influence is also fleeting. Keith Obermann, the central personality at MSNBC for years, quit the network and can no longer be found on air.
