Abstract:

Purpose
The purpose of this paper is to identify governmental social media use in cities with enhanced information and communications technology infrastructures (i.e. Informational World Cities) and high Internet penetration rates. Social media platforms are increasingly being used by governments to foster user interaction and it was investigated if social media platforms are valuable tools for reaching high numbers of citizens.

Design/methodology/approach
This paper is based on an iterative content and Web analysis from November 2012 till January 2013 and offers a comparison of different social media service types and the particular use.

Findings
This empirical investigation of 31 Informational World Cities provides an overview of social media services used for governmental purposes, of their popularity among governments and of their usage intensity in broadcasting information online. Even as cities in a globalized world become more similar, a variety in the use of social media by governments was detected, which is due to regional and cultural characteristics.

Research limitations/implications
The findings are limited to calculable data, e.g. number of used social media accounts, posts and followers which were available through a content and Web analysis at the time of investigation.

Practical implications
A more detailed content analysis, as well as a more differentiated analysis of users, must be conducted in the future.

Originality/value
This paper is one of the first that presents a global comparison of governmental social media use of cities of the knowledge society and compares different social media platforms.
