The marketing crowd can now test the commercial waters of MySpace. The News Corp.-owned social network on Monday introduced its MyAds advertising platform, giving the site’s 76 million users a do-it-yourself ad service, per BrandRepublic. The service allows MySpace users to create self-styled advertisements to promote their small business or professional services, which will target other MySpace users based on their profiles. MyAds works on a per-click basis.
