Unlock TV's Halo Effect to Boost Your Marketing Impact
TV advertising can have a halo effect, meaning it boosts performance on other marketing channels. The article explains that many marketers underestimate TV’s influence because attribution often emphasizes last-click results. Tatari researchers measure this effect by dividing website traffic into two groups: visitors who viewed a TV ad within the previous seven days and those who did not, then comparing conversion rates. Across 100 brands with social marketing-driven traffic, Group A’s CVR tended to be higher than Group B’s. Nine out of ten brands saw higher CVRs when exposed to TV ads; 60% of companies saw a CVR lift greater than 50%; and 33% saw a lift above 100%. The piece argues that campaigns should balance performance with reach, since broader TV exposure can amplify digital channels and raise overall brand impact. The data suggest TV can double or even triple conversion rates when aligned with digital efforts.

Comcast Research: TV Amplifies Recall, Engagement, Conversions
Comcast Advertising published new research titled "TV Makes Memories" showing that TV (traditional and streaming) acts as a full-funnel driver that strengthens other channels. The study reports that pairing TV with search yields up to 8.7× higher ad recall, with smaller lifts when paired with social (1.8×) and podcasts (1.6×). Adding TV increased downstream actions: TV + social raised website visit likelihood by 110%, TV + search raised brand discussion by 119%, and TV + audio raised information-seeking by 207%. The research also found search recall falls 23% when AI-generated summaries are used, suggesting TV helps brands remain top-of-mind as discovery becomes more automated.
Threads tests Gems to honor valuable posts daily
Threads is testing a new feature called Gems, which awards up to 25 outstanding conversations daily with a visible diamond badge. The selection is algorithm-based, focusing on originality, timeliness, and authentic discussion, regardless of follower count. Posts or direct replies qualify, but reposts and content cross-posted from Instagram are excluded. The feature is currently limited to public US-based accounts of users aged 18 and older, though the badges are visible globally, including in Germany. Recipients get a notification and can share the badge. Users can hide the label if desired. Initial hints appeared in August via app researcher Alessandro Paluzzi. Threads aims to encourage original and engaging content, with no negative impact on reach for non-recipients.
Meta Bans TikTok Ads on Its Platforms in Multiple Regions
Meta has banned advertising for TikTok on its platforms (Instagram, Facebook, WhatsApp) in several countries, including the USA, Japan, Vietnam, Canada, Egypt, Indonesia, and Thailand. This action, confirmed by Meta spokesperson Chris Sgro, prevents both ByteDance and third-party advertisers from promoting TikTok within Meta's ecosystem. The ban is seen as a competitive move amidst escalating rivalry between Meta, ByteDance, and YouTube. It may also be linked to Meta's recent $16.7 billion settlement with US states over youth safety, which includes conditions that require competitors like TikTok and YouTube to implement similar protective measures, suggesting a strategic pressure tactic to ensure they share the cost and responsibility of child safety initiatives.
