Norway Tightens Rules on Marketing to Children

Norway has introduced a strict law that limits the marketing of unhealthy food and drinks to anyone under 18. The regulation covers multiple channels, including online and media platforms, and targets products high in sugar, salt, and fat. The goal is to reduce the influence of advertising on children’s eating habits and long-term health. The policy applies broadly, including to international companies operating in Norway. While widely supported for public health reasons, it has also raised concerns among businesses about scope and interpretation.

Why It Matters

Regulation is moving beyond privacy into content control. Marketers in food, retail, and consumer goods must now factor in stricter rules on audience targeting, creative design, and channel selection. Read more.

Today's Insight: Inside Alphabet’s Advertising Engine

Alphabet’s advertising business is built on three core pillars: Search, YouTube, and its Display Network. Search remains the largest driver, capturing high-intent users and generating the majority of revenue. YouTube plays a different role, focusing on video engagement and brand storytelling at scale, with over 2 billion logged-in users. The Display Network extends reach across millions of websites, allowing advertisers to stay visible beyond owned platforms. AI is now central across all three, improving targeting, bidding, and ad relevance. While Search dominates today, YouTube and AI-led formats are shaping future growth.

Key Takeaways

  • Search captures intent and drives the largest share of ad revenue

  • YouTube delivers scale through video and creator-led content

  • Display extends reach across third-party sites

  • AI improves targeting, pricing, and performance across channels

  • Future growth depends on balancing intent, engagement, and reach
