The prize, awarded by marketing agency Precedent Communications, includes a new website, web training and a digital strategy. Entrants were invited to create a short video explaining why they should win and what difference the prize would make to their organisation.
The Children's Hospices UK video features three children doing a presentation on why the charity should win the prize.
Tom de Pass, head of communications at Children's Hospices UK, said the prize would help the charity increase its online presence.
Six charities were short-listed for the prize. The remaining five – the Prostate Cancer Research Foundation, Calm, the Guinness Trust's XCentre project, IntoUniversity and LearnAsOne – will receive training bursaries from the Media Trust.
All 60 video entries can be viewed on the competition microsite.
