21 channels will simultaneously broadcast the film, entitled Our Stories, that showcases their contributions to the daily lives of many across the UK.

Carolyn McCall, Chief Executive of ITV, said: “Our mission is to tell stories that reflect the diversity of life today in our nations and regions.

“From the excitement of our big entertainment shows, to the power and creativity of dramas and soaps to the depth and breadth of our documentaries and national and regional news and sport, our focus is reflecting a full range of experiences, bringing people’s lives centre stage and providing insight into how we see ourselves as well as how we look out into the wider world.”

Alex Mahon, Chief Executive of Channel 4, added: “This film is an incredible celebration of British storytelling and the beautiful, harrowing, funny and necessary stories we collectively share with the audiences we serve.” 

The film will journey through familiar landscapes and famous landmarks, while capturing historic moments from UK television on the country’s ubiquitous screens.

The overall message is one of unity, pride, and the important part the broadcasters play in building both through storytelling: “This is the story of everything we’ve done. And everything we could be. This is us. This is who we are. Our stories are your stories.”

“The importance of PSBs is clear to see in this turbulent world,” said Channel 5’s Director of Programmes, Ben Frow. “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.”

Simon Pitts, Chief Executive of STV, commented: “The variety and quality of the content of PSBs represents all aspects of people’s lives, from our news and current affairs, to drama to our leading entertainment, we make a unique contribution to British life. This film showcases and celebrates the richness of this contribution.”

“British free to air television - commissioned from the UK and produced in the UK – is here for everyone,” added Tony Hall, BBC Director General. “We do something special for the UK and provide authentic British programmes that our rivals simply don’t offer.”

Our Stories will air across the BBC, ITV, Channel 4, Channel 5, and on each broadcasters’ additional channels tonight at 8.58pm. It will also continue to play across all channels throughout the month.
