Guardian News & Media today announced that its media, education and society sections will no longer be printed as separate supplements.
The three sections, known as the "G3" supplements, will instead be published within the main body of the paper with immediate effect, following what was described as a 'successful'six-week summer trial.
GNM said it had received 'positive feedback'from readers and advertisers, who enjoyed 'more prominent exposure to their audiences".
Guardian editor-in-chief Alan Rusbridger said: 'Our specialist coverage of media, society and education is widely respected and an important part of our journalism.
'Bringing this into the heart of the paper has been well received by readers and advertisers, and as a result we've decided to continue with the move.
'At the same time we are developing our web content including creating a comprehensive Cutswatch database of how public sector cuts are being implemented around the UK."
In June, Rusbridger said The Guardian would become a 'digital-first'organisation, with future investment and effort focused on digital rather than print.
A month later GNM took the decision to scrap international print editions of The Guardian and The Observer. The last editions – printed New York, Frankfurt, Madrid, Malta and Cyprus – will be printed on 1 October 2011.
In an announcement released this afternoon GNM said it had created 11 new 'professional online networks'that had signed up close to 80,000 members.
They covered teachers, social enterprise, housing, local government, sustainable business, government computing, public leaders, higher education, the voluntary sector, healthcare and general careers.
Three new networks for professionals in social care, media and culture will be launched shortly.
Director of business and professional Colin Hughes added: 'The change means that specialist coverage of these important areas is placed more prominently in the paper, which we believe will be better for readers and advertisers.
'Feedback from agencies and clients over the summer has been positive, and readers have responded well in our research.
'In print, recruitment advertisers are increasingly looking for employer branding and capturing the attention of 'passive' job seekers, which is now more powerfully achieved in the main paper.
'We will also be using the sections on Monday, Tuesday and Wednesday to connect closely with our developing online activity.
'It is clear that the demand from our professional readers is for even greater in-depth coverage of their field online – a demand we have answered by developing, to date, 11 new professional networks, with a further three to be launched soon."
