Core Insights - The National Advertising Division (NAD) determined that Procter & Gamble's (P&G) claims regarding Crest 3D Whitestrips effectively removing years of stains are substantiated [1][3] Company Overview - Procter & Gamble (P&G) competes in the oral care market with its Crest 3D Whitestrips, which come in various versions differing in hydrogen peroxide concentration, application duration, and treatment count [2] - The product labels highlight specific claims such as "Removes Years of Stains in Just 1 Hour" and "Removes 10 Years of Tough Set-In Stains" [2] Product Efficacy - P&G's Crest 3D Whitestrips utilize hydrogen peroxide to eliminate intrinsic yellowing from teeth, a type of discoloration that regular brushing or dental cleaning cannot address [2] - P&G provided four meta-analyses indicating that intrinsic yellowing is primarily influenced by age, establishing a consistent rate of yellowing known as the Yellow Slope Value [2] - Additionally, P&G submitted four clinical studies demonstrating the effectiveness of its products in reducing teeth yellowness, which allowed for the calculation of years of stain removal based on product efficacy and the Yellow Slope Value [2] Regulatory Outcome - The NAD concluded that P&G's claims regarding the removal of years of stains by Crest 3D Whitestrips were adequately supported by the evidence presented [3] - P&G expressed appreciation for NAD's reasoning and consistent application of standards in its advertiser statement [3]

Core Points - The National Advertising Division (NAD) upheld AT&T's "AT&T Guarantee" for internet and wireless connectivity outages in response to a challenge from Charter Communications [1] - NAD recommended modifications to other claims related to the "AT&T Guarantee" found on AT&T's website and in March Madness commercials [2] Summary by Sections Knowing You Exist Commercials - The commercials feature life situations that are "not guaranteed" and introduce the AT&T guarantee, emphasizing connectivity, deals, and service [3] - NAD concluded that consumers are unlikely to interpret the guarantee as covering all outages, understanding that "making it right" pertains only to covered outages [4] March Madness Commercials - Charter challenged a series of commercials aired during NCAA March Madness, which set up a contrast between "not guaranteed" situations and the AT&T guarantee [5] - The commercials suggest that outages will be fixed quickly and that customers will receive compensation, with claims of "NETWORK INTERRUPTIONS FIXED FAST" and "GET A FULL DAY OF CREDIT" [6] Disclosure Issues - NAD found that the existing disclosure of material limitations to the guarantee was not clear and conspicuous due to its small font and busy visuals [7] - The guarantee's promise of quick fixes is not supported, as outages must last at least 20 or 60 minutes to qualify for compensation, which could be disruptive [8] Recommendations for AT&T - NAD recommended that AT&T clearly disclose the limitations of the guarantee and modify advertising to avoid misleading messages about fixing all outages quickly [9][12] - The first reference to the AT&T guarantee on the website was found to lack accompanying disclosures, leading to recommendations for clearer communication [11] First and Only Claims - NAD determined that AT&T's claims of being the "first and only carrier" to provide guarantees for wireless and fiber networks were unsubstantiated [13] - AT&T did not provide evidence to support these claims, and NAD recommended discontinuation of such statements [14]

Core Viewpoint - The National Advertising Division (NAD) found that Verizon's claims regarding its Satellite Texting services and "largest network" advertising were partially supported but recommended modifications for clearer disclosures in future advertising [1][5][8]. Satellite Claims - NAD reviewed Verizon's claims that it is "conquering dead zones with satellite" and found that these claims do not imply exclusivity over the functionality [2][3]. - The partnership with AST SpaceMobile, currently in testing, does not substantiate the claims made by Verizon regarding satellite texting [3]. - A previous commercial's disclosure about satellite connectivity was deemed insufficiently clear regarding the requirement for newer phone models [4]. - NAD concluded that while Verizon has a reasonable basis for its satellite claims, future advertising must include clear and conspicuous disclosures about the availability of satellite texting features [5]. "Largest Network" Claims - T-Mobile challenged Verizon's claim of having "America's largest network," arguing that this typically refers to geographic coverage rather than subscriber numbers [6]. - NAD found the term "largest network" ambiguous and noted that "postpaid phone connections" may not clearly indicate Verizon subscribers [7][8]. - NAD recommended that Verizon modify its disclosure to clarify what "postpaid phone connections" refers to, ensuring that the claims can be substantiated with appropriate qualifications [8]. Compliance and Discontinuation - Verizon has permanently discontinued the challenged implied claims related to satellite-supported texting and its wireless network, and NAD will treat these claims as recommended for discontinuation for compliance purposes [9]. - Verizon stated it will comply with NAD's recommendations regarding advertising practices [9].
