Notes
Additionally, through the Flowgo.com property, advertisers have access to powerful beyond the banner mechanisms, including opt-ins, newsletters, and pre-loaders, to effectively target their audience and reach consumers who are looking to be diverted and entertained, and thus are more open to advertising.
