Trinity Mirror is adopting cloud computing systems for email, collaboration and documents, switching to Google Apps.
The company, which publishes the Mirror and Daily Record newspaper, as well as local papers including the Manchester Evening News, will move its 6,500 staff on 60 locations to the new systems.
Google Docs are also used by Trinity Mirror media rivals the Guardian, the Telegraph and ITN.
It expects to improve processes and productivity, with the system transition, by eliminating administrative processes such as managing inboxes and merging document changes with colleagues.
Trinity Mirror also expects the collaborative features in Google Apps to improve team work, and to enable quicker project creation without a need for IT department involvement each time.
Its staff will have access to Gmail with integrated Google Talk, Google Calendar, Google Docs for document creation and Google Sites for creating web pages.
Trinity Mirror said employees will be able to collaborate in real-time from any location and any internet-connected device.
One of the reasons behind the move was that many staff already used the consumer version of Google Docs, and said they found it easier.
"We expect the real-time, collaborative features of Google Apps to enable us to make some real changes to the way we work, leading to a more productive workforce and helping us to become more profitable and innovative," said Steve Walker, Google Apps manager at the company.
Trinity Mirror also expects that by using Google Search, staff will be able to find information quickly and easily.
"For the many journalists in the business who work on tight deadlines and need to find the latest and most relevant information at the drop of a hat, this should prove invaluable," Walker said.
The move will be completed this month. Trinity Mirror is also planning a new intranet built on Google Sites.
