CTV vs Broadcast TV Cost Comparison for Law Firms

The broadcast sales rep will show you a $20 CPM and compare it to CTV’s $40. You’ll think you’re saving money. You’re not. You’re paying to reach 500,000 households when maybe 30,000 of them have any chance of ever needing your firm.

That’s not efficiency. That’s waste with a good cover story.

The Sticker Price Comparison

Here’s the number everyone sees first.

Medium	Typical CPM
Broadcast TV (local)	$15-30
Cable TV	$12-25
CTV (programmatic)	$25-40
CTV (premium direct)	$40-60

CTV looks more expensive. But CPM is cost per thousand impressions. It doesn’t measure cost per relevant impression. The deeper CTV vs broadcast advertising comparison shows why raw CPM is misleading.

What Targeting Actually Costs You

This is where the math gets interesting.

Broadcast reaches everyone in your DMA. The retired teacher who hasn’t driven in three years. The college student who bikes everywhere. The family in the next county who’d never drive to your office. You’re paying for all of them.

CTV lets you narrow to households in your service area, with relevant behavioral signals, matching your actual client profile. The waste drops dramatically.

The Effective CPM Calculation

This is the number that should be on every media comparison. Not nominal CPM. Effective CPM.

Here’s how the math works for a mid-size DMA.

Broadcast scenario: You buy $10,000 worth of local broadcast at $20 CPM. That’s 500,000 impressions across the DMA. Maybe 20% land in your actual service area. Of those, perhaps 30% have any relevance to PI services. Relevant impressions: 30,000. Effective CPM: $333.

CTV scenario: You spend $22,500 at $45 CPM. That’s 500,000 impressions. With geographic targeting, 90% are in your service area. With behavioral targeting, 60% have relevance indicators. Relevant impressions: 270,000. Effective CPM: $83.

Nine times the relevant reach. The higher CPM isn’t more expensive. It’s dramatically cheaper per person who matters.

Completion and Attention

Broadcast audiences leave the room during commercials. They check their phones. They flip channels. Nielsen estimates vary, but actual commercial attention during broadcast runs significantly below the raw ratings.

CTV ads don’t have that problem. They aren’t skippable. Viewers watch 94-96% of CTV ads to completion. Your full 30-second message lands. Every time. Personal injury lawyer advertising depends on message delivery. A 5-second glimpse before a channel change doesn’t build the trust needed for someone to call.

Measurement: The Unbridgeable Gap

This is where broadcast can’t compete at all.

Capability	Broadcast	CTV
Confirmed delivery	Estimated (ratings)	Verified (impression logs)
Completion tracking	Not available	94-96% tracked
Website visit attribution	Not measurable	Verified visits
Call tracking	Basic (vanity numbers)	Connected attribution
Optimization mid-flight	Minimal	Real-time adjustments
ROI calculation	Guesswork	Data-supported

With broadcast, you’re spending $50K/month and hoping it works. With CTV, you know which households saw the ad, whether they visited your site, and whether they called. Measuring law firm marketing ROI is only possible when the channel gives you data to work with.

Minimum Investment Comparison

CTV often requires a lower entry point, especially in major markets where broadcast time slots are expensive.

Market Size	Broadcast Monthly Min	CTV Monthly Min
Small DMA	$15-25K	$12-20K
Mid DMA	$30-60K	$25-45K
Major DMA	$75-200K	$50-80K

Broadcast minimums are driven by unit costs. Primetime spots in a major market might run $2,000-5,000 each. You need enough spots per week to build frequency.

CTV minimums are about achieving meaningful reach and frequency against your target audience. Because you’re not buying from the waste, the threshold is lower.

The Flexibility Factor

Broadcast locks you in. Four-to-eight-week flights, committed budgets, cancellation penalties. If the creative isn’t working or your intake team is overwhelmed, you can’t pause.

CTV offers month-to-month commitments at most platforms. Pause and resume capability. Real-time targeting adjustments. Creative swaps mid-campaign. For firms testing CTV for the first time, that flexibility matters.

Where the Audience Actually Is

Nielsen’s latest data tells the story clearly. Streaming now accounts for 44.8% of all US TV viewing. Broadcast has dropped to 21.4%. Cable sits at 27.3% and falling.

The audience moved. Where $150 million in legal advertising goes each month shows that most legal ad dollars haven’t followed. The majority still goes to broadcast. That disconnect is the opportunity.

Firms that shift budget toward where people actually watch TV get more efficient reach. It’s not a prediction. It’s arithmetic.

Total Program Cost Comparison

For a mid-size market, annual totals look closer than you’d expect.

Category	Broadcast	CTV
Media spend (annual)	$600K	$480K
Creative production	$30K	$30K
Management/platform	Included	$72K
Attribution/tracking	Minimal	$8K
Branded search protection	Often neglected	$50K
Total	~$630K	~$640K

Similar total investment. But CTV gives you household-level targeting, verified attribution, and real-time optimization. Broadcast gives you a ratings estimate and a prayer.

When Broadcast Still Makes Sense

Broadcast isn’t dead. In some situations it still earns its place.

Sports events with massive live audiences. Older demographics who haven’t adopted streaming. Markets where broadcast viewership remains above 30%. Name recognition campaigns where blanketing an entire DMA is the goal.

But for most PI firms in 2026, the shift from broadcast to streaming isn’t aggressive. It’s overdue.

The Hybrid Approach

Some firms run both. Broadcast for broad awareness, CTV for precision targeting and measurement. The two channels can complement each other when budgets allow.

The key is measurement. With CTV, you can measure. With broadcast, you estimate. When budget gets tight, cut the channel you can’t measure first. That means broadcast goes before CTV. Every time.

The Hybrid Question

Some firms run both:

• Broadcast for broad reach
• CTV for targeted precision
• Combined presence

This can work with sufficient budget. But don’t run broadcast just because “we’ve always done it.”

The Trend Direction

Viewership continues shifting:

• Streaming: 44.8% and growing
• Broadcast: 21.4% and declining
• Cable: 27.3% and declining

Following the audience to CTV isn’t aggressive. It’s necessary.
