One of the most important features relevant to the impact of new technologies on electoral campaigns is the significant increase in the number of actors in the campaign, independent from the parties. Communication is no longer centralised, with just one individual source (be that a politician, party or media body) communicating with a large audience of individuals, but decentralised, with many individual sources communicating with the audience of individuals. Today anyone can show support for a particular candidate online, upload a video with critical content or send emails promoting a candidacy without any official relationship to the campaign. However, these activities may have a much greater impact on the final outcome of the campaign, causing a qualitative change, and can lead to controversies.
