The company's 'Art of Outdoor' contest aims to discover "the most innovative digital outdoor advertising" that includes full motion, subtle motion and interactivity.

The winner has the chance to win a share of a £250,000 prize fund as well as having their entries showcased across four of Ocean Outdoor's high profile locations that include Eat Street @ Westfield, Holland Park Roundabout, Two Towers East and Two Towers West.

Industry judges involved in the competition include Kinetic UK head of digital Carolyn Nugent, Ocean Outdoor CEO Tim Bleakley and Pavlos Themistocleous, head of digital creative at OgilvyOne.

Ocean Outdoor marketing director Richard Malton said: "The collective knowledge of our expert jury spans every area of the advertising business and allows for a balanced and reasoned critique for each and every entry."
