The Advertising Standards Authority wants to create clearer guidelines for vloggers and brands, according to Guy Parker, its chief executive, speaking at today's ISBA annual conference. Parker said the move follows its ban on ads for Oreo that starred YouTube vloggers, in November. The vloggers did not indicate clearly enough that they were being paid by Mondelez to feature Oreos in their videos. He said vloggers want help from the ASA on understanding the guidelines between advertising and editorial.
