Cassy Hayes and Jasmine Coleman were among the first fans to arrive outside the Ronald Reagan UCLA Medical Center in Los Angeles where Michael Jackson was brought and later pronounced dead. How had Hayes, 25, and Coleman, 21, heard the news so quickly? Twitter. The two young women had learned about Jackson's health like so many who get their news nowadays: by reading the ever-flowing feed of real-time information on the microblogging service. Jackson's unexpected death at 50 was just the latest major news event where Twitter played a central role. But just as quickly as Twitter has emerged as a news source, so, too, has its susceptibility to false rumors become abundantly apparent. Twitter's constantly updating record of up-to-the-minute reaction has in some instances threatened to usurp media coverage of breaking news. It has also helped many celebrities, athletes and politicians bypass the media to get their message directly to their audience. Twitter has in many ways been a boon to the media. It's one more way a story might go viral and it's arguably the best way for a news outlet to get closer to their readership. Most outlets now have a presence on Twitter with a feed directing readers to their respective sites. But even in an Internet world that has for years eroded the distance between media and consumer, Twitter is a jolt of democratization to journalism. Many users have become accustomed to clicking on Twitter when news breaks. There, they can find a sea of reaction, commentary and links to actual articles. The popular technology blog TechCrunch recently questioned whether Twitter is “the CNN of the new media generation.” “Twitter absolutely changes the media landscape,” said Ross Dawson, author and communications strategy analyst. Ashton Kutcher, one of Twitter's most popular users, in an earlier Web video evoked the rhetoric of a revolutionary: “We can and will create our media.” But there are no follow-up questions on Twitter if the user chooses not to hear them. When tweets replace an interview or a press conference, something is lost. While involvement in the protests in Iran might be Twitter's most meaningful achievement thus far, some have noted that many inaccuracies were circulated. That has raised the concern that some people or governments may use Twitter to spread disinformation. Truthfulness remains the biggest problem: Those direct, near-instantaneous dispatches are far less reliable than old-fashioned journalism. News that circulates on Twitter, re-tweeted from person to person, can spread quickly – often too quickly for it to be verified. False rumors spread daily on Twitter.
