CA SB921

Enacts the Digital Advertisement Transparency and Accountability (DATA) Act to create a state-run archive of digital political advertisements for state candidates and ballot measures.

Requires online platforms receiving $50,000 or more monthly from digital advertisement sales to submit records of digital ads purchased by committees spending $500+ annually to the Fair Political Practices Commission by the 5th of each month.

Digital advertisement records must include a copy of the ad, approximate views, display dates/times, spending information, candidate/measure details, and committee identification number.

Commission must maintain submitted information in a centralized, publicly accessible online format with search capabilities, filters, and raw data download options for at least 12 years.

Eliminates existing online platform disclosure requirements for platforms subject to the new digital advertisement submission requirements once the commission certifies its system, 60 days after which the new requirements become operative.
