Nintendo Switch leads with a notable rise in Ad Awareness, moving from 10.3% on May 30 to 18.4% on June 25, an increase of 8.1 percentage points. This surge is attributed to the launch of the Nintendo Switch 2 on June 5, 2025. The release was supported by a summer sale on digital games via the Nintendo eShop offering discounts on a wide selection of first-party titles. 

Dunkin' follows with an increase of 5.2 percentage points, rising from 26.0% on May 29 to 31.2% on June 25. The brand’s Ad Awareness growth may be linked to its collaboration with pop star Sabrina Carpenter to launch a new summer beverage, Sabrina's Strawberry Daydream Refresher. This marks Carpenter's second collaboration with Dunkin', following the release of her Brown Sugar Shakin' Espresso in December 2024. Alongside the new refresher, Dunkin' introduced several summer-themed menu items, including ice cream-inspired frozen coffees and a $5 meal deal.

Starbucks rounds out the top three with a gain of 5.1 percentage points, increasing from 31.1% on May 26 to 36.2% on June 25. The increase is likely driven by the return of its popular Double Chocolate Brownie after discontinuing it in May 2025. Responding to strong customer feedback, Starbucks reintroduced the brownie to stores nationwide in June. Additionally, Starbucks launched a limited-time beverage, Firework Frappuccino.

Methodology: YouGov BrandIndex collects data on thousands of brands every day. A brand’s Ad Awareness score is based on the question: “Which of the following consumer brands have you seen an advertisement for in the past two weeks?” (% Yes). Data from surveys of adults aged 18 years and above residing in the US from 26 May to 25 June 2025. Ad Awareness scores are based on a four-week moving average. The change in scores for each brand is calculated by taking the difference between the highest and lowest scoring days within the period.
