Daniel Romero, a Ph.D graduate from Cornell University, measured the influence of all the news media accounts on Twitter, using what he calls the Influence-Passivity Algorithm and came up with a list of the Top 100 influential news media accounts on Twitter. His research data included all tweets containing a URL from June 15th through July 22nd of 2009.
Romero found out that “having a large number of followers does not imply having influence in news social media. Furthermore, not having a large number of followers does not mean lack of influence.” … “to be influential on Twitter news media networks have to keep their audience engaged through valuable tweets and not simply convince people to “follow them on Twitter.”
The list comes after the jump!
