Chairman and Chief Executive Officer of News Corp., Rupert Murdoch stated that newspaper publishing houses must stop search engines such as Microsoft Corp and Google Inc. from presenting full articles for display and that too for free of cost.

Murdoch, who prints the Wall Street Periodical and Times of London, said that news aggregators must be able to show only a caption, a couple of quotes or sentences and the alternative to subscribe to the journal or magazine.

Murdoch also said that in order to make their trades work, public houses, including New York Times Co.'s flagship daily, have to put up pay walls on the Internet to charge the readers who want to access their content.

Murdoch said that he has two computer screens in his workplace which are capable of displaying wsj. com and nytimes. com throughout the day so he can evaluate and compare the news on different sites.

Google, which is based in Mountain View, California, has stated that public houses can limit to five a day the amount of editorials a reader can access for free of charge through its search and news services.
