Amid ongoing focus on how social media and other companies approach online advertising, California’s latest effort to require disclosure of online advertising will take effect January 1. We blogged on these revisions to the California DISCLOSE Act, sometimes called the Social Media DISCLOSE Act, when they passed back in 2018. Absent federal action, we expect to see the states continue to push into this area, potentially requiring online ad disclosure and imposing requirements on advertisers or campaigns to keep a file or record of online ads they place or display.
