, created by London design agency Bose Collins, will allow greater sponsorship and display opportunities for brands with video wraps, full site takeovers, pre-rolls and advertorials on every page.
The site now also allows users to create their own profiles, create their own channels using hand-picked clips and import their other social media profiles into their Kontraband profile.
Richard Spalding, chief executive of the Kontraband Group, said: "This is a very exciting time for Kontraband; our focus over the last three years has been growing our audience and delivering for our advertising partners.
"As UK leaders in this highly sought after demographic we now have the opportunity to provide brands with fully integrated digital bespoke campaigns that fit their specific needs. In addition, we continue to extend our user offering and have a number of further exciting developments that we plan to announce throughout the course of the year."
The Xbox sponsorship was bought and planned by Universal McCann and Ad2one.
