Revenue-sharing ad network Adjix launched an ad format that lets users embed text ads within "tweets" (Twitter posts). When users use Adjix2Twitter to post to their Twitter accounts, a small text link appears at the end of their tweet. The linker must approve the ad before it is sent. See video demonstration. Advertisers can set accounts up so anyone can run their ads. Conversely, ads can be limited to certain Twitter accounts. Brands can also decide how frequently an ad runs, either on an account or in given locations, writes MarketingVOX.
