CTV wins the screen. The phone wins the sale.

Streaming now owns the living-room screen. But nobody buys anything with a TV remote — and every major platform is quietly building a bridge to the device already in the viewer’s hand.

This week MediaPost’s Wayne Friedman asked the question every TV seller dreads: can connected TV ever become a performance channel like search and social? His answer, roughly: probably not in the way people hope. Signals are inconsistent across platforms, viewers rarely buy straight after a TV ad, and CTV’s real value sits higher in the funnel — paid off later, through search and social.

He’s right about the symptom. But the cause isn’t measurement alone. It’s the hardware. The TV is the best attention device ever built and one of the worst transaction devices. The action happens on the phone. The platforms know it — and their product roadmaps prove it.

The audience has already moved

The attention argument is settled. In June, streaming reached 48.5% of all US TV viewing in Nielsen’s Gauge, with cable down to 19.5%. The single biggest platform on the TV glass isn’t a studio: it’s YouTube, at 13.5% — up from 12.8% a year earlier, while Netflix slipped to 7.9%.

Spain shows the same picture from the other side of the corridor: connected TV reaches 95% of internet users aged 16–75 — about 34 million people — and ad investment grew 48.4% in 2025 to around €175 million, with IAB Spain forecasting another 30–60% this year.

Why the TV can’t close the sale

Interacting with a television is hard by design. Four technical facts explain most of the “CTV can’t do performance” debate:

• A 10-foot interface. TV UIs are built to be read from the sofa and driven with a directional pad. Typing an address, comparing products or filling a form with a remote is slow enough that almost nobody does it.
• A shared screen. The TV is a household device. There’s rarely a single logged-in individual in front of it, so there’s no clean identity to attribute to — or to sell to.
• No wallet at hand. The phone has saved cards, biometrics and one-tap checkout. The TV has, at best, a QR code pointing back to the phone.
• Fragmented signals. Every streamer, smart-TV maker and ad-tech vendor tracks differently. As InterMedia Advertising’s David Nyurenberg put it in an AdExchanger column, CTV “still has technical barriers that don’t exist in the same way on search and social.”

Spain’s data shows where the action actually goes. Nearly half of CTV viewers (47%) use a second device while watching, almost always a smartphone, and three in four of them are on social media. Only 9% search for the product they just saw, and only 5% have ever scanned a QR code from a CTV ad — down from 6% a year earlier. On the buy side, 52% of professionals say the lack of metrics validating results is what holds back more investment; just 13% track purchase intent and 7% store visits.

The viewer’s attention is on the big screen. Their thumb is on the small one. That’s where the sale lives.

What the streaming platforms are building

Look at what the platforms shipped this year and a pattern jumps out: none of them is betting that people will buy with the remote. They’re taking one of two routes — hand the action to the phone, or close the loop with retail data so the viewer never has to act on the TV at all.

The only “buy on the TV” that works is Amazon’s — precisely because the TV is borrowing an identity and a wallet that were built on the phone and the web.

The money is moving slower than the audience

If attention has moved, budgets are following at a much less certain pace. IAB’s buy-side survey projects US CTV ad spend up 13.8% in 2026. Madison & Wall’s forecast is far cooler: national digital TV up just 3% to $21.0 billion, after 12% growth in 2025, with total TV advertising down 2.4%. The two aren’t measuring exactly the same thing — one surveys buyers’ intentions, the other projects national digital TV excluding political ads — but the gap says something: buyers want CTV, and they’re still waiting for proof that it sells.

That proof won’t come from a better remote. It will come from connecting the TV exposure to what happens next on the phone.

The only players already on both screens

Here’s what the CTV debate keeps missing. The platform winning the TV screen is YouTube — which means a large and growing share of what people watch on their televisions is creator content. And what those same viewers do on the second screen is social media.

Creators are the one form of media that already lives on both screens, with the same audience, the same face and the same voice. A sports creator’s long-form video plays on the living-room TV; their clips, links, codes and community live on the phone. The hand-off the platforms are engineering with QR codes and “send to phone” buttons, creators already do natively.

What brands and platforms should take from this

• Plan CTV for attention, not clicks. Judge it on reach, incremental reach and lift — then measure the outcome where it happens: search, social and site traffic on mobile.
• Design every TV ad for the hand-off. If there’s a call to action, make it a phone action. A QR code nobody scans is not a strategy; a reason to look down at the phone is.
• Buy the bridge, not just the screen. Creator partnerships that run on TV and mobile give you both halves of the funnel with one audience — and a cleaner signal than stitching two separate buys together.
• In Spain and Latin America, move now. Penetration is near-universal, investment is growing fastest of any digital format, and measurement is still immature. The brands that learn cross-screen attribution first will set the benchmarks everyone else buys against.

Friedman asked whether CTV can become a performance channel. Wrong question. CTV is where the audience pays attention. The phone is where it acts. The winners will be whoever connects the two — and creators got there first.
