Limitations of media and the internet as a public sphere
Some, like Colin Sparks, note that a new global public sphere ought to be created in the wake of increasing globalization and global institutions, which operate at the supranational level. However, the key questions for him were, whether any media exists in terms of size and access to fulfil this role. The traditional media, he notes, are close to the public sphere in this true sense. Nevertheless, limitations are imposed by the market and concentration of ownership. At present, the global media fail to constitute the basis of a public sphere for at least three reasons. Similarly, he notes that the internet, for all its potential, does not meet the criteria for a public sphere and that unless these are ‘overcome, there will be no sign of a global public sphere’.

German scholar Jürgen Gerhards and Mike S. Schäfer conducted a study in 2009 in order to establish whether the Internet offers a better and broader communication environment compared to quality newspapers. They analysed how the issue of human genome research was portrayed between 1999 and 2001 in popular quality newspapers in both Germany and the United States in comparison to the way it appeared on search engines at the time of their research. Their intention was to analyse what actors and what sort of opinions the subject generated in both print and the Internet and verify whether the online space proved to be a more democratic public sphere, with a wider range of sources and views. Gerhards and Schäfer say they have found ‘’only minimal evidence to support the idea that the internet is a better communication space as compared to print media’’ ‘’In both media, communication is dominated by (bio- and natural) scientific actors; popular inclusion does not occur’’. The scholars argue that the search algorithms select the sources of information based on the popularity of their links. ‘’Their gatekeeping, in contrast to the old mass media, relies mainly on technical characteristics of websites’’. For Gerhards and Schäfer the Internet is not an alternative public sphere because less prominent voices end up being silenced by the search engines’ algorithms. ‘’Search engines might actually silence societal debate by giving more space to established actors and institutions’.
