This study examines how the watchdog concert in journalism field has been created and develope4 Related studies found that the watchdog is related not so muck with free press theory as with a privilege awarded to the press because the press serves for the public interests. It was found that in the U.S., the watchdog concept was derived from the a lot of libel cases in the late 1890s. At the time, the newspaper owners and editors continuously claimed the very protection over vulnerability of newspaper's collecting, reporting, and printing news. While, in Korea, the concept of watchdog emerged in the late 1990s after the establishment of the Constitution Court. Even though the watchdog concert was accepted very late by the Korean courts, it is believed to be a kind of special privilege to prevent the press from being recklessly regulated in libel cases. Rather, the Korean courts expand the extent of the role of the press as a watchdog by deciding that not only the public officials and politicians but also other socially influential public figures could be included in the criticism from the press. However, how these court decisions can be practically implemented depends upon how the court apply the probability of the press to believe the news true and intention of malice in writing and publishing the stories.

As hostile online reviews can have a negative impact on a company's reputation, it is not surprising that online reviewers and business owners often get involved in conflicts which sometimes evolve into legal disputes. This research examines the legal dispute case in which the business owner charges an online reviewer for a defamation. Further, this research compares the supreme court's decision with general public's view on this defamation case, using a survey method. From the legal point of view, an online reviewer's primary motive determines whether the online reviews are defamatory statements or not. Specifically, if an online reviewer's primary motive is to increase the overall benefits for the public society, the online review does not bear any legal liability. According to our survey, consumers' view aligns with the final decision of the supreme court. They believe that online reviews should bear a minimum level of legal liability as online reviews often contain useful and valuable information which can enhance overall public benefits.
