Will the mass media of the 21st century available to ordinary citizens produce positive pragmatic poltical action on a global scale?

let me explain... the innovation of a global library (internet) of knowledge has made the world smaller than ever, this cannot be denied. Will the nationalist demeanour of the 20th century be transformed into something greater? Is "Globalist" a feasible political ethos in the next century? Will humans become more conscious of the suffering of others due to greater global access to media or will it serve simply as means of further disillusioning the electorate in order for the financial hegemons to retain political prowness?
