What it is

Xfinity can share your personal information with its corporate siblings including NBCUniversal and Sky, not just within Xfinity itself.

Consumer impact (what this means for users)

This provision means your Xfinity browsing history, TV viewing data, and personal details may be shared with NBCUniversal and Sky for their own marketing and advertising purposes, far beyond what most consumers expect from a cable and internet provider.

What you can do

⚠️ These actions may provide transparency or partial mitigation but may not fully address the underlying issue. Effectiveness varies by jurisdiction and individual circumstances.

Institutional analysis (Compliance & legal intelligence)

(1) REGULATORY FRAMEWORK: This provision implicates the Cable Communications Policy Act (47 U.S.C. § 551(c)(1)), which requires explicit opt-in consent before a cable operator discloses personally identifiable information — including viewing history — to third parties, with enforcement authority held by the FCC and private right of action available to subscribers. CCPA/CPRA (Cal. Civ. Code § 1798.115) requires disclosure of third-party sharing categories and opt-out rights for sale or sharing of personal information. EU GDPR Art. 6 and Art. 13 require a lawful basis and transparent disclosure for each data controller receiving personal data. (2)
