Several studies provide evidence that the Internet-community, particularly bloggers, can push their own agenda into public agenda, then media agenda, and, eventually, into policy agenda. In the most comprehensive study to date, Wallsten tracked mainstream media coverage and blog discussion of 35 issues during the 2004 presidential campaign. Using time-series analysis, Wallsten found evidence that journalists discuss the issues that bloggers are blogging about. There are also anecdotal pieces of evidence suggesting bloggers exert an influence on the political agenda. For instance, in 2005 Eason Jordan, the chief news executive at CNN, abruptly resigned after being besieged by the online community after saying, according to various witnesses, that he believed the United States military had aimed at journalists in Iraq and killed 12 of them. Similarly, in 2002, Trent Lott had to resign as Senate majority leader due to his inappropriate racist remarks that were widely discussed in the blogosphere. However bloggers attract attention not only to oust journalists and politicians. An online investigation on technical problems with electronic voting machines started by an activist Bev Harris in 2003 eventually forced traditional media outlets to address issue of electronic voting malperformance. This in turn made Diebold, a company that produces these machines, to acknowledge its fault and take measures to fix it. Many studies have been performed to test the agenda setting theory within global news coverage. One of the findings determined that foreign news that had any mentions of the United States or the UK, greatly influenced public opinion compared to global news that didn't involve either country.
