NBCUniversal tested deepfake detection technology from startup Reality Defender, stemming from the company's LIFT Labs Generative AI Accelerator in 2023, to explore solutions for protecting its outbound content from AI-generated manipulation in the public space.

Reality Defender's platform uses a multimodal approach to detect AI-generated or manipulated audio, video, images, and text. As a result of the LIFT Labs Accelerator — a program where Comcast NBCUniversal partnered with select startups — Reality Defender began piloting its technology with NBCUniversal specifically to explore ways to secure NBCUniversal content circulating publicly. Comcast also participated in Reality Defender's $15 million Series A funding round in October 2023. The status of the pilot beyond initial testing is not confirmed by available sources.
