Missing People has found 100 people who were featured on a digital billboard since the campaign launched last year.

Since it was launched by Kate McCann in July 2012, more than 270 weekly appeals for missing people have appeared on digital billboards that have been donated by members of the trade body, Outdoor Media Centre.

Missing People is able to control the campaign from its office and target regional appeals based on a person’s last known whereabouts. Adverts include a photo of the missing individual and contact details.

Jo Youle, chief executive of Missing People, said: “Digital billboards have proven to be an immensely powerful tool in the search for missing people, particularly young or vulnerable people. Finding 100 people safe and well is a great achievement and we are enormously grateful to the Outdoor Media Centre and their members.”

The partnership is reviewed on an annual basis and is set to continue until at least July 2014. Outdoor Media Centre estimates that media value is more than £10m.
