London site Flavorpill claims to reach 45,000 readers a week through its events newsletter.
Mark Mangan, co-founder and chief executive of Flavorpill, awarded the UK online ad sales account to w00t media because the sales house already works with other digital lifestyle sites in the UK.
Flavorpill was originally a weekly music events newsletter for New York. It now publishes 10 e-mail bulletins and claims to reach 750,000 readers in New York, Los Angeles, San Francisco, Chicago and London.
Drum & Bass Arena claims to reach more than 1.2 million users every month. The site offers drum and bass fans downloadable podcasts, music releases, remixes and sells merchandise.
Ad sales on Drum & Bass Arena were previously handled by Dolphin Digital. Karl Nielson, commercial director at Drum & Bass Arena, said w00t media had more sites with niche appeal and so was better positioned to sell Drum & Bass Arena.
Nielson said w00t media was an agency that "we feel understands the creation of campaigns that go beyond the traditional banner format".
W00t media currently handles the sales of cultural websites Urban Junkies, Don't Stay In, Clash Music, London Parties and Playboy.
