The Streaming Gap in Legal Advertising, DMA by DMA

Streaming captured 47.5% of all US television viewing in December 2025, according to Nielsen’s The Gauge. That same month, it surpassed combined broadcast and cable for the first time in history. Not close. Not tied. A clear majority of where Americans actually watch TV now lives on connected devices.

Legal advertisers, as a category, put roughly 20% of their budgets there.

We track legal advertising spend across 210 US markets on a 24-million household panel. Firm by firm. Channel by channel. The data tells the same story in nearly every DMA: the audience moved to streaming, and the ad dollars didn’t follow. The national average sits between 20% and 22% CTV allocation for legal services. That’s a 25-point gap between where people watch and where law firms advertise.

This isn’t a rounding error. It’s the single largest misallocation in legal advertising today.

The 27-Point Gap

Here’s the math. Nielsen reports 47.5% of total TV time goes to streaming. Our data shows legal advertisers nationally allocate 20% to 22% to CTV. The difference is 25 to 27 percentage points of audience that legal ads simply don’t reach through their primary viewing channel.

Context makes this worse. 89.2% of US households will have CTV access by 2026, according to eMarketer. 83% of adults already use at least one streaming service. 70% say streaming is their primary way to watch television. 3.6 million homes cut the cord in 2023 alone.

The audience isn’t splitting between broadcast and streaming. It’s migrating. And legal advertisers are spending the majority of their TV budgets on the side of the split that shrinks every quarter.

Where the Money Actually Goes

Nationally, legal advertising is a $2.9 to $3.2 billion category projected for 2026. The channel mix across 210 tracked markets looks roughly the same everywhere, with a few dramatic exceptions.

Broadcast dominates because it’s always dominated. Media buyers have broadcast relationships. Firms have broadcast creative. Agencies earn broadcast commissions. The infrastructure is built for a channel that now delivers a quarter of total viewing.

That inertia is the gap.

The DMA Scoreboard

Not every market looks the same. Some have started closing the gap. Most haven’t. A few are so far behind that the streaming opportunity borders on absurd.

We publish deep-dive breakdowns on dozens of individual markets. Here’s the CTV adoption rate for legal advertising in 13 of them, ranked from worst to best.

Look at the bottom of that list. Washington DC runs 3% CTV. Three percent. In a market where 47.5% of television viewing happens on streaming platforms. That’s a 44-point gap between audience behavior and ad placement.

Boston sits at 9%. Dallas at 10%. These aren’t small markets. They aren’t unsophisticated. They’re some of the largest, most competitive legal advertising DMAs in the country. And they’re placing nine out of every 10 TV ad dollars on channels that capture barely half the audience.

The Outlier That Proves the Rule

Atlanta tells a different story. At 48% CTV allocation across $12.9 million in monthly legal ad spend, Atlanta is the only major market where legal advertisers have nearly closed the streaming gap.

Seven of Atlanta’s top 10 advertisers put more than 50% of their budgets into streaming. Thompson Law runs 68.7% CTV. Dozier Law Firm hits 81.3%. These aren’t experiments. They’re primary channel strategies from firms spending $400K to $1.4 million monthly.

Atlanta didn’t get here by accident. Market growth of 118% brought new advertisers who started on streaming instead of inheriting broadcast contracts. Younger demographics pushed firms toward the platforms their audience actually uses. Competitive pressure did the rest. Once several major firms committed to CTV, the holdouts faced a choice: follow or disappear from where half the audience watches.

Every other market will go through this same transition. The question is timing.

Why Broadcast Holds On

The streaming gap isn’t irrational. It’s structural. Understanding why it exists is the first step toward exploiting it.

Buying relationships run deep. Media buyers have 20-year broadcast relationships. Shifting budget to CTV means renegotiating, sometimes with entirely different vendors. Inertia favors the channel you’ve always bought.

Creative doesn’t transfer cleanly. A 30-second broadcast spot and a 15-second CTV pre-roll serve different contexts. Firms running broadcast-only creative need to invest in CTV-native production. That’s a real cost, even if it’s a one-time one.

Measurement gaps persist. Broadcast offers reach estimates. CTV offers household-level impressions, completion rates, and attribution. Ironically, the channel with better measurement gets less budget because the existing reporting infrastructure is built around broadcast GRPs.

Commission structures favor broadcast. Some agencies earn higher margins on broadcast buys. The incentive to shift clients toward CTV isn’t always aligned with the agency’s revenue model. That’s not a conspiracy. It’s just math.

None of these reasons are good enough to justify a 27-point audience gap. But they explain why it persists.

Five Markets Where the Gap Creates Opportunity

Not all streaming gaps are equal. Some markets combine low CTV adoption with high total spend, creating outsized opportunity for the firm that moves first. Here are five.

Washington DC: 3% CTV, $2.6M Monthly

The most extreme gap in our data. DC’s legal advertising market runs 73% broadcast and 3% streaming. Morgan and Morgan controls 31% of the market. Almost nobody has claimed CTV inventory for legal services in the nation’s capital.

A firm deploying $100K monthly into DC streaming would own the category overnight. Zero competition. Premium audience. Government employees, federal contractors, and suburban professionals who stream more television than nearly any other demographic.

Boston: 9% CTV, $3.2M Monthly

Boston’s 9% streaming rate sits at the bottom of comparable Northeast markets. Morgan and Morgan owns 30% share. Local heavyweights Jason Stone and Keches Law run 0% CTV. Not low. Zero.

The math isn’t complicated. $3.2 million monthly, 9% to streaming, means roughly $288K in total CTV spend across the entire Boston legal market. One aggressive firm could match the entire market’s streaming spend with a single budget line item.

Dallas: 10% CTV, $6.9M Monthly

Dallas runs $6.9 million monthly with Thomas J. Henry controlling 35% share. CTV allocation is 10%. That’s $690K in streaming spend across 148 tracked advertisers. In the fifth-largest DMA in the country.

Thomas J. Henry’s dominance is almost entirely broadcast. His brand recognition comes from repetition on traditional channels. A CTV-first challenger wouldn’t compete head-to-head on broadcast. They’d reach the streaming audience that Henry’s ads never touch.

Philadelphia: 12% CTV, $4.6M Monthly

Philadelphia’s $4.6 million market dedicates 34% to radio and 12% to streaming. That radio number is second only to Houston among major markets. The CTV gap here is compounded by heavy radio allocation, meaning legal advertisers are split between two traditional channels while streaming inventory sits wide open.

New York: 11% CTV, $14.5M Monthly

The largest legal advertising market in the country puts 11% of its spend on streaming. That’s roughly $1.6 million in monthly CTV spend across the entire New York DMA. For perspective, a single Atlanta firm (Thompson Law) spends nearly $1 million monthly on Atlanta streaming alone.

New York isn’t underserved because the market is small. It’s underserved because the broadcast infrastructure is so deeply entrenched that the shift hasn’t started.

Why CTV Performs

The streaming gap wouldn’t matter if broadcast and CTV delivered equivalent results. They don’t.

CTV ads are non-skippable on most platforms. Completion rates exceed 95%. Compare that to YouTube at 15% to 25% and social video at 5% to 15%. When someone sees your CTV ad, they watch the whole thing.

Targeting is the real differentiator. Broadcast reaches everyone in a DMA. CTV reaches specific households based on demographics, income, location, and behavior. A personal injury firm can target homeowners aged 25 to 54 in specific zip codes who’ve searched for legal topics. Our complete CTV guide for law firms covers every targeting layer available on streaming platforms today. Broadcast can target “adults 25 to 54 in the Dallas DMA.” The precision difference is enormous.

Roku’s 2025 attention research found that 81% of Gen Z considers ads a fair trade-off for free streaming content. 48% of all consumers say they respond to streaming TV ads. That’s not passive viewing. That’s active engagement.

The Cost Question

Every CMO’s next question: what does CTV actually cost compared to broadcast?

CTV CPMs (cost per thousand impressions) typically run $25 to $45 for legal services, depending on market size and targeting precision. Broadcast CPMs in major markets range from $15 to $30 for prime inventory but deliver far less targeting.

The real comparison isn’t CPM. It’s cost per qualified household reached. When broadcast delivers a ~25% target audience hit rate and CTV delivers ~70%, the effective cost per relevant impression favors streaming even at higher face-value CPMs.

Our full CTV cost breakdown covers CPM ranges, monthly budget tiers, and ROI benchmarks from the 210 markets we track. The short version: a firm spending $50K to $100K monthly on CTV in a market with 10% legal ad streaming adoption will dominate that channel’s legal inventory.

The Atlanta Roadmap

Atlanta’s 48% CTV adoption didn’t happen overnight. It followed a pattern that every other market will eventually repeat.

Phase 1: Early movers. A few firms test CTV with 10% to 20% of budget. Results outperform broadcast on a per-impression basis. They increase allocation.

Phase 2: Competitive response. Local competitors notice the early movers appearing on streaming platforms. They allocate budget to avoid ceding the channel entirely. Adoption climbs from 15% to 30%.

Phase 3: Structural shift. CTV becomes table stakes. Firms that don’t run streaming look absent from where half the audience watches. Budget splits stabilize around 40% to 50% CTV. Firms in this phase typically rely on dedicated law firm CTV media services to manage frequency, creative rotation, and attribution at scale. Atlanta is here.

Most major legal markets are still in Phase 1 or haven’t started at all. DC, Boston, and Dallas are pre-Phase 1. Houston and Charlotte are entering Phase 1. Los Angeles and Las Vegas have reached Phase 2.

The firm that enters any market during Phase 1 gets the cheapest inventory, the least competition, and the longest runway to build brand recognition on the platform before rivals show up.

The Concentration Multiplier

The streaming gap gets worse when you factor in market concentration. We showed in our analysis of legal advertising concentration that the top 10 firms nationally control 29% of spend. These dominant advertisers are overwhelmingly broadcast-heavy.

Morgan and Morgan, the largest legal advertiser in the country at $17.2 million monthly across 23 markets, runs a broadcast-first national strategy. When the market leader in your DMA puts 60% or more into broadcast, two things happen. Broadcast inventory gets expensive because the biggest buyer is competing for it. And streaming inventory stays cheap because the biggest buyer isn’t there.

This is the concentration multiplier. The more a dominant advertiser leans into broadcast, the wider the streaming gap becomes in that market, and the bigger the opportunity for everyone else.

In Houston, Jim Adler spends $1.21 million monthly. Zero on CTV. That’s $1.21 million competing for broadcast and radio inventory while leaving streaming completely open. In Dallas, Thomas J. Henry’s $2.4 million monthly broadcast strategy creates the same dynamic.

What $3.2 Billion Looks Like in 2027

CTV represents roughly one-third of all TV ad spend nationally, growing at about 20% annually according to eMarketer. Legal advertising as a category sits well below that average. The gap will close. The only question is how fast.

If legal CTV adoption grows from 20% to 35% nationally over the next 18 months (following the trajectory of other verticals), that represents $350 to $500 million in annual legal ad spend shifting from broadcast to streaming.

That money has to go somewhere. It’ll flow into programmatic CTV buys, premium streaming placements on platforms like Hulu and Peacock, and connected TV targeting strategies that didn’t exist five years ago.

The firms that build CTV infrastructure now, creative, targeting, measurement, and attribution, will capture that shift. The firms that wait will pay more for the same inventory once every competitor discovers it.

The Market-by-Market Playbook

Every DMA is different. The streaming gap creates different opportunities depending on total market size, current CTV adoption, dominant advertiser behavior, and audience demographics.

Here’s how to read the data for your market.

Gap above 30 points (DC, Boston, Dallas, New York, San Francisco, Philadelphia): These are first-mover markets. CTV inventory for legal services has almost no competition. Entry costs are low. The risk isn’t that CTV won’t work. It’s that you’ll own so much of the category that scaling takes time. Start at $50K to $75K monthly. Test creative. Build measurement. Scale from there.

Gap between 20 and 30 points (Houston, New Orleans, Charlotte, Chicago): Competition is emerging but thin. Two to three firms in each market have started CTV buys. This is early Phase 1. $75K to $150K monthly gives you meaningful market presence. You won’t own the category outright, but you’ll be among the first few serious CTV advertisers.

Gap under 15 points (Atlanta, Los Angeles, Las Vegas): The window for cheap entry has closed. These markets have real CTV competition. Budget requirements jump to $150K to $300K monthly for comparable share of voice. The opportunity still exists, but it’s competitive rather than greenfield.

The Bottom Line

We’ve published deep-dive market breakdowns on more than 30 DMAs. The pattern repeats in every one. Legal advertisers over-index on broadcast. Streaming sits underfunded. The audience keeps migrating.

47.5% of TV viewing goes to streaming. Legal advertisers put 20% there. That’s the gap. It’s measured. It’s documented. It exists in every market we track.

Atlanta proves the gap can close. Thompson Law, Dozier, and Dennis Law Firm prove that CTV-first strategies work at scale. The remaining 209 markets prove that most legal advertisers haven’t figured this out yet.

The audience already moved. The question for your firm is straightforward: follow the audience, or keep buying broadcast inventory at premium prices while the people you’re trying to reach watch something else.

Nobody’s going to send you a memo when your market hits Phase 2. By then, the first-mover advantage is gone.
