It is well accepted that there is no single precise definition of political communication since 'political' and 'communication' themselves have varieties of definitions. In order to critically discuss the changes that the Internet has brought to political communication, this essay will define political communication as intentional communication about politics (McNair, 2011: 4). As McNair (2011:6) and Norris (2010) state, political communication involves the interactive process between political organizations, media and citizens. Furthermore, the media is a crucial element that connects political organizations and citizens in various ways. Downward communication from political organizations to citizens, horizontal communication between parties, public organizations, pressure groups, terrorist organizations and governments, and upward communication from citizens to political organizations require the media to disseminate information. Media includes print, broadcast and online channels. With the development of information technology and the Internet, online channels are becoming increasingly important for political communication. This essay focuses in particular on the changes that the Internet has brought to political communication. First, some positive impacts that the Internet has brought to political communication will be explained.

Furthermore, the Internet can convey some politicians' personal preferences to the public and win over potential supporters. For example, Cameron posted a tweet glorifying what David Beckham did for England in 2013. This type of tweet allows citizens to learn more about Cameron and potentially gain support from Beckham fans even if they hadn't voted for Cameron previously. In conclusion, the Internet serves as a new platform for politicians to make political advertising and circulates abundant and positive information to prevent defamatory competition and corruption..
