AI And Streaming Are Rewriting Advertising in 2026

Automation Is Moving From Support Tool To Default Setting

Big Tech platforms are steadily reducing the need for manual campaign management. Meta continues to expand Advantage+, while Google is embedding AI deeper into campaign setup, optimisation and creative delivery.

EMARKETER describes this shift as an “existential threat” for agencies. When media buying and optimisation happen inside the platform, traditional agency roles inevitably shrink.

For e-commerce brands, this lowers entry barriers. Campaigns are easier to launch and scale. The trade-off is less hands-on control.

Streaming Will Take 49.3% Of Video Subscription Revenue

Streaming services are projected to generate 49.3% of US video subscription revenues in 2026. At the same time, total pay TV (traditional and digital combined) will decline to 48.0% in 2027.

This shift is also driven by pricing. The average US cable TV subscription costs $122 per month, according to J.D. Power. Individual streaming services are cheaper, but as households stack subscriptions, total spending is overtaking traditional TV.

European markets are following the same direction, with ad budgets increasingly moving toward connected TV and digital video.

YouTube Keeps Its Lead In Video Podcasts

Video podcasts are becoming mainstream, and YouTube remains in front.

In 2026, the platform is expected to reach 31.7 million monthly podcast viewers in the US, ahead of Spotify.

For brands, this confirms that long-form video content combined with creator-led distribution is not a niche channel anymore — it is becoming a core media format.

AI Search Is Reducing Click Opportunities

Search behaviour is also changing. After the introduction of AI Overviews in Google Search, zero-click searches fell by 17% between May 2024 and May 2025, based on Similarweb data cited by EMARKETER.

The report also shows click-through rates dropping by several percentage points when AI summaries appear.

For publishers, this means fewer referral visits. For e-commerce brands, it signals a more competitive paid search environment and greater pressure on owned media.

What E-commerce Leaders Should Watch

The takeaway is not about chasing every new channel. It is about understanding where control is shifting.

Automation is becoming standard. Streaming is nearly level with traditional TV. YouTube is consolidating video attention. And AI search is reshaping traffic patterns.

In 2026, the brands that adapt fastest to these structural changes — rather than short-term trends — will hold the advantage.
