The publishing group today bought the video site for an undisclosed sum and plans to offer advertisers options to reach Kontraband's 2.2 million unique users together with readers of the likes of Monkey and iGizmo.
Dennis has created several digital only publications in recent years including lads mag Monkey, tech title iGIzmo and iMotor and last year bought tech website bit-tech.net and current affairs site thefirstpost.co.uk.
James Tye, chief executive of Dennis Publishing, said that Kontraband will sit well in the publisher's portfolio, especially with lad's digital mag Monkey.
The acquisition comes 10 years on from the founding of Kontraband as an email attachment of funny clips sent by friends. It has since developed into a website offering charts of the web's funniest videos, movie clips, games and amusing ads.
Advertising provides revenue for Kontraband with brands able to buy homepage placements as well as run a series of formats including interactive banners.
But the rise of YouTube has made life tough for smaller sites of a silmilar ilk. Kontraband's unique users once topped 10 million but are now under the three million mark.
Richard Spalding, co-founder of Kontraband, said that Diffusion Media Group, Kontraband's holding company will now focus on social media and viral seeding through its other division, The 7th Chamber.
