Course Description

Digital advertising has changed the nature of how companies connect with their customers. Social media and related tools — native advertising, the use of hashtags, and the shift to interacting through mobile devices — have given rise to a host of new legal challenges and corresponding risks.

This course, taught by Cobalt Law LLP Partners Tsan Abrahamson and Nate Garhart, provides an overview of the issues in this area facing brand owners. The speakers also provide practical advice for mitigating risk as companies expand their marketing into this new landscape. Some of the subjects that will be covered include: Hashtags (how to properly use them and avoid confusion or misleading advertising), Native Advertising, Raffle Laws, the California Eraser Law and California Privacy Act, the Telephone Consumer Protection Act, and the role of Testimonials and Endorsements in advertising.

Learning Objectives: 

  1. Articulate the myriad legal issues that affect business owners using digital advertising techniques
  2. Understand how to properly utilize hashtags, testimonials, and endorsements
  3. Advise clients on the interaction between Federal and California-specific laws and regulations
