San Antonio is the seventh-largest city in the US. It added 23,900 residents from 2023 to 2024, the fourth-fastest growth rate among major American cities (US Census Bureau, 2025). The metro area holds 2.5 million people. Joint Base San Antonio is the Department of Defense’s largest joint installation. It contributed $55 billion to the Texas economy in 2023 alone (Texas Comptroller, 2024).
Yet the San Antonio legal advertising market tells a smaller story than the city’s size suggests. Nielsen ranks San Antonio as DMA 31, with 1.1 million TV households. Monthly legal ad spend sits at $2.53 million. Compare that to Houston’s $7.2 million or Dallas’s $6.9 million. San Antonio spends roughly a third of what its Texas neighbors do.
That gap isn’t a weakness. It’s the opening.
Thomas J. Henry’s Home Court
Every Texas legal advertising market has a Thomas J. Henry story. In Dallas, he controls 35% at $2.4 million monthly. In Houston, he spends $834K. But San Antonio is where it all started.
Thomas J. Henry Law is headquartered here. The firm operates from San Antonio with offices in Corpus Christi, Austin, Dallas, and Houston. His advertising strategy works the same across every market. Dominate broadcast. Own the airwaves. Build the kind of name recognition that makes people dial a number from memory.
In San Antonio, Henry spends $666K monthly. That captures 26.3% of the market. It’s a lower share than his 35% in Dallas, but there’s context. San Antonio is his headquarters city. He’s been on local airwaves here since the firm’s earliest days. Texas Public Radio investigated how Henry makes money given his massive ad spend, concluding that the advertising itself is the engine. “The reason he makes so much money is because he spends so much on advertising” (Texas Public Radio, 2024).
Nationally, Thomas J. Henry ranked as the second-highest spender on spot TV among all law firms in 2024, investing an estimated $21.4 million (American Tort Reform Association, 2025). San Antonio is just one piece of a multi-market Texas strategy.
A Fragmented Field
Remove Henry from the picture, and San Antonio’s legal ad market fractures.
The dropoff is severe. Davis Law Firm, the number two advertiser, spends less than a quarter of what Henry does. “Call the 4s” is their San Antonio tagline, but $154K monthly doesn’t carry the same weight as $666K.
Herrman and Herrman, a Corpus Christi firm that expanded into San Antonio, sits at $128K. Jim Adler, “The Texas Hammer,” runs $102K here. That’s a fraction of his $1.21 million Houston budget. Dimopoulos Injury rounds out the top five at $89K.
44.9% of all San Antonio legal advertising comes from these five firms. The other 55% scatters across dozens of smaller advertisers. Nobody between positions six and twenty commands more than 3% of the market.
That fragmentation matters. It means the path to becoming the number two advertiser in San Antonio isn’t a $500K monthly commitment. A firm spending $200K could reshape the competitive landscape overnight.
Where the Money Goes
Broadcast dominates San Antonio. Four stations divide the inventory: KENS (CBS), WOAI (NBC), KSAT (ABC), and KABB (Fox).
63% broadcast. That’s higher than Houston’s 47% and slightly above Dallas’s 61%. It reflects Henry’s preferences. When the market’s biggest spender allocates heavily to broadcast, the aggregate tilts that way.
Cable at 15% stands out. Dallas runs 9%. Houston barely registers at 1%. San Antonio advertisers still see value in cable inventory, likely because local cable buys offer cheaper frequency in a mid-market DMA where broadcast CPMs aren’t as steep as Houston or Dallas.
CTV at 22% is the number worth watching.
22% CTV in a Market That Should Be Higher
San Antonio’s 22% streaming allocation lands right at the national average for legal advertising. It matches Tampa’s 22%. It exceeds Dallas’s 10% and Houston’s 18%.
But averages lie. Nationally, streaming captured 47.5% of all TV viewing in December 2025, according to Nielsen’s The Gauge. On Christmas Day, it hit 54%. Four platforms set personal bests that month (Nielsen, 2026).
San Antonio’s population skews young and military-connected. The city’s median age falls below the Texas average. Joint Base San Antonio’s personnel and their families number in the hundreds of thousands. Younger demographics stream more. Military families move frequently and tend toward streaming-first households.
A 22% CTV allocation in a market with this demographic profile isn’t adequate. The audience has moved. The ad dollars haven’t caught up.
The Texas Broadcast Culture Problem
San Antonio isn’t unique among Texas markets in its broadcast dependence. It’s a pattern.
Houston allocates 47% to broadcast plus 34% to radio. Dallas runs 61% broadcast plus 20% radio. San Antonio puts 63% on broadcast plus 15% on cable. The theme repeats: Texas legal advertisers built their brands on traditional media, and they aren’t letting go.
Three factors drive this.
Car culture. Texas cities sprawl. San Antonio covers 505 square miles. Commuters spend hours in cars, and radio plus broadcast habit loops reinforce traditional advertising. Edison Research consistently finds AM/FM radio commanding 86% of ad-supported in-car listening.
Established relationships. Firms like Thomas J. Henry have decades-long relationships with local station sales teams. Those relationships come with preferred rates, bonus spots, and make-goods that don’t translate to programmatic CTV buying.
Proven ROI on traditional. Henry’s strategy works. You don’t spend $21.4 million annually on spot TV if it doesn’t produce signed cases at scale. The challenge isn’t that broadcast fails. It’s that streaming reaches audiences broadcast misses, at lower CPMs, with better targeting.
The Math for a Challenger
Here’s where San Antonio gets interesting for a firm willing to think differently about law firm advertising budgets.
Total CTV spend in San Antonio: $557K monthly. That’s the entire streaming budget for every legal advertiser in the DMA combined. A firm allocating $75K per month to San Antonio CTV would capture 13.5% of all legal streaming inventory in the market.
At $30 CPM, that $75K buys 2.5 million household impressions monthly. The DMA has 1.1 million TV households. That’s more than two impressions per household per month on unskippable, big-screen, 15- or 30-second spots.
Compare the competitive environment. On broadcast, a challenger competes against $1.59 million in legal ad spend, $666K of it from Henry. On streaming, the same challenger competes against $557K total. Less crowded. Lower CPMs. Better targeting.
The CTV budget guide by market size breaks down how mid-market DMAs like San Antonio offer favorable unit economics compared to top-10 metros.
Growth at 19%
San Antonio’s legal ad market grew 19.1% year-over-year. That added $406K in monthly spend over the prior period. Strong growth. Not quite Houston’s 20%, but ahead of most markets nationally.
Where does that growth go? Into the same channels. Broadcast gets more. Cable gets more. The established players scale their existing buys. Henry’s $666K represents his San Antonio allocation. If the market grows another 19% next year, his share holds steady unless someone changes the competitive equation.
ATRA’s 2024 national report documents the larger trend: $2.5 billion in annual legal advertising across 26.9 million ads, up 39% since 2020 (American Tort Reform Association, 2025). San Antonio’s growth tracks this national acceleration.
The question isn’t whether the market keeps growing. It will. The question is whether new dollars flow into the same traditional channels or whether someone redirects them to streaming.
What Henry’s Strategy Tells You
Thomas J. Henry built a multi-market Texas empire on broadcast saturation. His approach is disciplined. Dominate the local broadcast schedule. Build name recognition to the point where your name is the first one people think of after a car wreck. Then scale it across every Texas DMA.
It works. Texas Public Radio documented the economics in detail (Texas Public Radio, 2024). Critics questioned the spending. The firm kept growing.
But Henry’s strategy has a specific limitation. It only works as long as the audience watches broadcast. Nationally, streaming passed broadcast in total TV viewing share in 2023 and hasn’t looked back. The trajectory is clear. Legal advertisers who built brands on broadcast will eventually face a shrinking audience for their most expensive channel.
Henry hasn’t made a meaningful CTV push in San Antonio. His budget concentrates on the four broadcast stations and cable buys. That leaves streaming inventory wide open for a firm willing to invest.
The 18-Month Window
Every major market trends toward higher streaming TV adoption for law firms. Atlanta went from roughly 20% CTV to 48% in two years. Houston climbed from 12% to 18%. The curve accelerates once three or four firms commit.
San Antonio sits at 22%. That number will climb. When it does, early movers lock in favorable inventory rates and audience targeting data. Latecomers enter a crowded, more expensive market.
A firm that establishes CTV presence in San Antonio today builds brand equity in a channel Henry hasn’t claimed. They reach the streaming-first households that broadcast misses. They target by zip code, income, age, and behavioral data in ways broadcast can’t match. And they do it for a fraction of what broadcast costs per impression.
$2.5 million monthly. 19% growth. One firm owns 26% and runs almost entirely traditional. The rest of the field is fragmented below 6%.
San Antonio’s legal advertising market isn’t complicated. It’s waiting.
