Newspapers, radio news reports, and new shows on broadcast tv are (and have always been) susceptible to bias. However, the desire to attract a large number of readers, listeners, and viewers of many different political positions most likely limited the amount of bias they allowed. The rise of new formats like cable television and social media has brought many more outlets through which people can learn about politics and world events. Because these can survive without appealing to everyone, they can afford to be more biased. And, because anyone can create a blog or tweet, uninformed people, including some with extreme views, can provide inaccurate information disguised as fact.
