By law, most political advertising must include a message that explains who paid for it (sponsor identification).  The law also dictates where and how the sponsor ID message is displayed.  Campaigns and most other advertising sponsors must report to the PDC how much money was spent on advertising, which candidates or ballot measures benefited from the advertising and, in some cases, when the advertising was presented to the public.  Most campaigns and sponsors will find that the brochures linked below have all of the information they need to comply with sponsor ID and disclosure requirements.
