Advertising Watchdog Upholds Xfinity's 'Fiber-Powered' Claim, Mandates Clearer Disclosure

NEW YORK — The National Advertising Division of BBB National Programs ruled on June 3, 2026, that Comcast can continue to describe its Xfinity internet service as “fiber-powered,” but recommended the company modify its advertising to make disclosures about its network technology clearer and more conspicuous. The decision came in response to a challenge brought by competitor AT&T Services, Inc., which argued the term was misleading to consumers.

The case was handled through the National Advertising Division’s (NAD) Fast-Track SWIFT process, an expedited system designed for single-issue advertising disputes. AT&T contended that the “fiber-powered” claim was insufficient to communicate that Xfinity’s service is not delivered entirely via fiber-optic cables to the customer’s location, a configuration known as Fiber-to-the-Home (FTTH). Instead, Xfinity primarily uses a hybrid fiber-coaxial network, where fiber runs to a neighborhood node and existing coaxial cables complete the connection into homes and businesses.

This ruling underscores a critical point for businesses of all sizes: the line between persuasive marketing and misleading advertising is thin, and crossing it can invite costly challenges from competitors and regulators. In our experience, many companies focus heavily on crafting compelling headline claims but neglect the fine print, viewing disclosures as a mere legal formality. This case proves that the placement, prominence, and clarity of those disclosures are just as important as the claim itself. Defending against an advertising challenge, even when successful, consumes significant time and resources and can create reputational risk.

In its decision, the NAD determined that the core language of Comcast's claim was not inherently deceptive. The division pointed to the advertiser's existing disclosure, which states that “Xfinity Internet is powered by fiber and connected to premises by coaxial cable.” According to the NAD, this wording sufficiently explains that the service is distinct from an end-to-end FTTH offering and clarifies the role of coaxial cable in the final delivery of the service.

However, the NAD found fault with the presentation of this disclosure. The investigation noted that in many Xfinity advertisements, the qualifying statement was bundled within a larger block of text containing unrelated information, such as pricing offers and other terms. This practice, the NAD concluded, reduced the disclosure's prominence and made it less likely to be noticed by the average consumer. Furthermore, in some digital ad formats, the disclosure appeared several panels away from the initial “fiber-powered” claim, forcing a user to scroll to find the clarifying information.

Consequently, the NAD recommended that Comcast modify its advertising to ensure the disclosure is presented in a clear and conspicuous manner, in close proximity to the claim it qualifies. Comcast stated that it would comply with the NAD’s recommendations, according to a report from Telecompetitor.

The dispute highlights the intense competition among internet service providers, where network technology has become a key marketing battleground. Companies like AT&T have invested billions in building out FTTH networks and are aggressively marketing the benefits of pure fiber, such as symmetrical upload and download speeds and greater reliability. The term “fiber” has become synonymous with premium, high-speed internet in the minds of many consumers and business owners, making its use in advertising a high-stakes issue.

For small and mid-sized businesses, the technical distinctions are significant. The choice of an internet provider can directly impact daily operations, from cloud computing and video conferencing to processing transactions and managing data backups. Understanding whether a service is FTTH or a hybrid fiber-coaxial network helps a business make an informed decision based on its specific needs for bandwidth, particularly upload speed, which is critical for businesses sending large files or using cloud-based applications.

The NAD operates as the U.S. advertising industry’s self-regulatory body. While its decisions do not carry the force of law, the vast majority of advertisers voluntarily comply with its rulings to maintain industry standards and consumer trust. The organization reviews advertising claims across a wide range of industries, from telecommunications and consumer electronics to healthcare and pharmaceuticals, helping to ensure a level playing field for advertisers.

Moving forward, industry observers will be watching to see how Comcast adjusts its advertising disclosures for the Xfinity brand. The ruling sets a precedent for other providers using hybrid networks, reinforcing that while they can highlight the fiber components of their infrastructure, they must do so with unambiguous and prominently placed disclosures that prevent consumer confusion.
