Media Influence. A Twitter Based Measure. Case Urdangarin. Allegations of Corruption Against Son-in-Law of King Juan Carlos of Spain

In this post we propose an indirect way to measure influence of news providers. We use Twitter as filtering criteria.

There are plenty of mechanisms, approaches and rankings concerning the most influential newspapers or news providers. Online difussion and social media proliferation is probably making these kind of analysis more difficult to achieve and less reliable. It is difficult to establish the weight and influence of online and offline editions of news providers like newspapers, radio stations, TV broadcasters and pure digital medial like blogs or pure online newspapers.

We propose here an indirect measure of influence of news providers from any source. The idea is to check which are the news providers used by Twitter users to refer to external sources for explaining or interpreting an event. Of course, this means that this restrict the analysis to only online editions of news providers, and not the original offline content, if existing. This means that the measure that we are proposing contain a number of caveats and limitations. But we consider that they do not undermine nevertheless the validity of the underlying intution: in a tweet, an user is constricted to choose a single external source, if any. Referring to an analysis or news offered by a news provider is a way taken by the Twitter user to show her position in the issue, and to share it with her followers and Twitter community. By picking this news provider, the Twitter user is showing trust and credibility to this chosen source. She is also expanding the area of influence of this news provider, as she is making it accessible to other Twitter users.

Thus, a way to measure which are the external references preferred by active social media users is to monitor news providers that have been used by Twitter users as external references during the period of time that an event or issue was active in social media arena, i.e., the event received a sustained amount of tweets inside this period of time.
