HBO Max has emerged as Norway’s leading Advertiser of the Month for August, followed closely by REMA 1000 and SPAR. According to YouGov BrandIndex, which tracks brand perception daily, these three brands achieved the highest increases in Ad Awareness among Norwegian consumers throughout August.

Ad Awareness is a key metric that measures whether consumers recall seeing an advertisement for a brand within the past two weeks. The difference between the highest and lowest scores during the month determines which brands stand out as top performers.

HBO Max saw the most significant growth in Ad Awareness this month, with an impressive increase of 11.1 percentage points. The brand’s score rose from 9.2% on August 1st to 20.3% on August 30th. This surge suggests that HBO Max’s recent campaigns have resonated strongly with Norwegian audiences, boosting the platform’s visibility and recall.

In second place is REMA 1000, one of Norway’s largest and most recognized supermarket chains. REMA 1000 experienced a notable rise of 8.3 percentage points, growing from 40.2% on August 1st to 48.5% on August 31st. This increase highlights the effectiveness of REMA 1000’s advertising efforts and its continued relevance in the competitive Norwegian grocery market.

Rounding out the top three is SPAR, another well-known supermarket chain in Norway. SPAR achieved an 8.2 percentage point increase in Ad Awareness, moving from 17.5% on August 9th to 23.0% on August 29th. This growth reflects SPAR’s successful marketing initiatives and its ability to capture consumer attention during the month.

These results underscore the dynamic nature of Norway’s advertising landscape, where both international streaming services and local supermarket chains are vying for consumer attention and recall.
