The Queen says the pandemic has shown the importance of the news industry as it provides 'trusted, reliable sources of information' in a dramatically changing world.
She highlighted the 'vital' public service role it has played, particularly given the proliferation of social media.
The sovereign also described the news industry's efforts to support communities as 'invaluable', thanks to campaigns, fundraising efforts and volunteering drives.
In a message to mark the launch of Journalism Matters Week, run by the News Media Association (NMA) trade body, she writes: 'The Covid-19 pandemic has once again demonstrated what an important public service the established news media provides, both nationally and regionally.

'As our world has changed dramatically, having trusted, reliable sources of information, particularly at a time when there are so many sources competing for our attention, is vital.'
The Queen added: 'The efforts of the news media to support communities throughout the United Kingdom during the pandemic have been invaluable - whether through fundraising, encouraging volunteering or providing a lifeline for the elderly and vulnerable to the outside world.'
In April, the Daily Mail launched Mail Force as an emergency response to the national shortage of personal protective equipment for frontline healthcare staff.
Donations poured in from tens of thousands of Mail readers and leading philanthropists, and the total has passed £11million.
Mail Force has since procured a vast range of PPE and sent tens of millions of items to grateful hospitals, care homes and charities around Britain.
The charity's funds now have been allocated to testing equipment on the basis that this is the most pressing issue when it comes to protecting healthcare staff.
