In a revamp scheduled for 4 March the broadsheet's finance section is to gain an extra page dedicated to media business and incorporating coverage from its online mediaguardian.co.uk site.
This is the first time that the paper has transferred an online offering to the main pages. The extra page will be edited by mediaguardian.co.uk journalist Dan Milmo and will run from Tuesdays to Fridays.
Media business is seen as a growth sector for the paper, despite the global downturn in PR, marcoms and advertising budgets.
Guardian PRO Isabel Milner said that it is believed the tabloid sports sections on Mondays and Saturdays have been received favourably by readers.
Similarly, the sport section is also to increase by a page, which will give more coverage for sport comment and features.
Other changes set to be included in next month's revamp include a daily page in the broadsheet section for the Editor, The Guardian's weekly round-up of global news that is published on a Saturday.
Edited by Michael Hann, this will become a daily round-up of global media.
The Saturday comment section is also to be increased by a page.
Meanwhile The Guardian has boosted its political coverage with the promotion of Sarah Hall to political correspondent.
Hall is a former Press Association parliamentary journalist who joined The Guardian as a general news reporter six years ago.
She previously covered the political correspondent role at The Guardian on a temporary basis, from late 2000 to February 2001, covering Lucy Ward's maternity leave.
Editor Alan Rusbridger said: 'These changes capitalise on somne of the Guardian's strongest elements - media, sport, comment and The Editor.'
