BBC, ITV, Channel 4 and Channel 5 have collaborated on a special film.
The unique project will see the four free to air broadcasters - and STV in Scotland - come together for the first time across 21 channels on Wednesday (08.07.20) at 8.58pm for a two minute project about the role the networks play across the UK's culture.
The 'Our Stories' campaign - which has been created with the help of Uncommon Creative Studio - will represent the way the broadcasters echo the lives across Britain and resonate beyond the small screen.
The short film will air in a one-off roadblock special on BBC One, BBC Two, ITV, Channel 4, Channel 5, STV, S4C, 4Seven, E4, More4, Film4, ITV2, ITV3, ITV4, ITVBe, 5STAR, 5USA, 5Select, Paramount Network, and BBC Four.
It will then continue to play across all channels throughout the month.
Tony Hall, BBC Director-General, said: "British free to air television - commissioned from the UK and produced in the UK - is here for everyone.
"We bring people together for the big moments - from a royal wedding to the World Cup. We are there at times of crisis and to provide comfort, laughter, education and entertainment.
"We do something special for the UK and provide authentic British programmes that our rivals simply don't offer."
Carolyn McCall, Chief Executive of ITV, added: "Our mission is to tell stories that reflect the diversity of life today in our nations and regions.
"We aim to engage with viewers from all walks of life."
Alex Mahon, Chief Executive at Channel 4, commented: "Channel 4 has a unique role to play in public service broadcasting - we were created to challenge the status-quo and in doing so tell the stories that otherwise may not be told.
"This mission and with it our commitment to super-serve the young audiences who place their trust in us and authentically represent and reflect the diverse experiences of people across the UK, has never felt more urgent and important."
And Ben Frow, Director of Programmes at Channel 5, commented: "We are proud to be part of this united campaign celebrating the role the BBC, ITV, Channel 4 and Channel 5 all play for the nation."
