Tubi is the largest free ad-supported streaming television (FAST) service in the United States. For law firms, Tubi represents the volume play: massive reach at lower CPMs, trading content prestige for advertising efficiency.
Tubi by the Numbers
| Metric | Value | Source |
|---|---|---|
| Monthly active users | 100+ million | Tubi announcement, June 2025 |
| Monthly viewing hours | 1+ billion (May 2025) | Tubi announcement |
| Share of total TV viewing | 2.2% | Nielsen’s The Gauge, May 2025 |
| Content library | ~300,000 titles | Tubi |
| Original productions | 400+ | Tubi |
That 2.2% of total TV viewing makes Tubi larger than Peacock (1.3%), Max, and Paramount+ (1.2%) in terms of household market share. Among free streaming platforms, only YouTube commands more attention.
The Tubi Audience
Tubi’s free model attracts a specific viewer profile:
Demographics:
- Over 50% Gen Z or Millennials
- 67% cord-cutters or cord-nevers
- Cost-conscious consumers who’ve opted out of paid streaming
- Slightly more diverse than traditional TV audiences
Viewing behavior:
- 95%+ of viewing is on-demand (not linear FAST channels)
- Nearly one in four viewers watch Tubi Originals
- 4-6 minutes of ads per hour (vs. 16+ minutes on traditional TV)
This audience composition matters for law firm targeting. Tubi viewers aren’t the affluent households watching prestige HBO content. They’re everyday people who’d rather deal with ads than pay $15/month for another streaming service.
For PI advertising specifically, this is often exactly who you want to reach, working-class and middle-class viewers who drive, work physical jobs, and don’t have lawyers on retainer.
CPM Ranges and Costs
Tubi sits in the value tier of CTV advertising:
| Platform Type | CPM Range | Examples |
|---|---|---|
| Premium | $35-55 | Netflix, Hulu direct |
| Mid-tier | $25-35 | Prime Video, Peacock |
| FAST/Value | $15-25 | Tubi, Pluto TV, Freevee |
Multiple sources confirm Tubi CPMs in the $15-25 range:
- Strategus reports $15-25 CPM for Freevee-class FAST platforms
- Tinuiti cites approximately $20 CPM, with agency partnerships potentially achieving 2-3x better efficiency
- Adwave confirms $15-30 CPM for typical small business campaigns
Compared to Hulu at $30-35 CPM or Netflix at $37+, Tubi delivers roughly twice the impressions per dollar. The tradeoff is content environment, library movies and TV versus next-day network programming. For a full pricing breakdown across platforms, see CTV advertising costs for law firms.
How Tubi Advertising Works
Tubi runs on CPM pricing with standard video ad formats:
Ad formats available:
- Pre-roll (before content)
- Mid-roll (during content breaks)
- Standard lengths: :06, :15, :30, :60, :90
Ad experience:
- Full-screen, non-skippable
- Professional streaming environment
- Integrated with content breaks (feels like traditional TV)
Targeting options:
- Demographics (age, gender, household income)
- Geography (national, DMA, zip code)
- Interest-based targeting through programmatic data
- Genre/content clustering
Tubi supports buying through multiple paths:
Direct (for large advertisers): Minimum campaign budgets reportedly start around $25,000, positioning direct buys for medium to large advertisers.
Programmatic: Most advertisers access Tubi through programmatic platforms (The Trade Desk, MNTN, StackAdapt, etc.) where Tubi inventory is aggregated alongside other streaming services. This is the typical path for law firms. Your CTV partner likely already has Tubi access.
Self-service platforms: Tools like Vibe.co and Adwave offer Tubi inventory with lower minimums ($50 in some cases), making it accessible for testing.
Tubi’s Ad Technology
Tubi has invested heavily in advertising technology, which benefits campaign performance:
Advanced Frequency Management (AFM): Tubi’s proprietary solution manages ad frequency across the platform. Early tests showed 366% reduction in over-frequency and significant reach increases. This matters because hitting the same viewer 15 times in a week wastes budget and annoys potential clients.
Measurement partnerships:
- VideoAmp for cross-platform measurement
- LiveRamp for identity resolution
- Comscore for audience verification
- Nielsen integration
- The Trade Desk integration
Data capabilities: Tubi can charge premium targeting rates because its free model generates rich viewing data. When you’re not paying for content, you’re providing behavioral data that makes targeting more precise.
When Tubi Makes Sense for Law Firms
Strong Use Cases
- Brand awareness at scale, $20K delivers 800K+ impressions
- Testing CTV, lower CPMs mean lower risk
- Younger demographics (25-44), Tubi over-indexes here
- Cost-conscious audience aligns with PI client profiles
- Complementing premium buys, Tubi for reach, Hulu for quality
Weaker Use Cases
- Premium brand positioning, library content won't impress
- Affluent targeting, high-income households prefer premium
- Older demographics, 55+ under-indexes on Tubi
- Geographic precision. Some local markets have limited inventory
Tubi vs. Other FAST Platforms
How does Tubi compare to similar free streaming options?
| Factor | Tubi | Pluto TV | Freevee | Roku Channel |
|---|---|---|---|---|
| Monthly users | 100M+ | 80M+ | ~50M | ~100M |
| Content model | 95% on-demand | Linear channels + VOD | On-demand | Mixed |
| Owner | Fox | Paramount | Amazon | Roku |
| CPM range | $15-25 | $12-22 | $15-25 | $20-35 |
| Data advantage | Viewing behavior | Paramount data | Amazon purchase data | Device + viewing |
| Ad load | 4-6 min/hour | Higher (linear) | Standard | Varies |
Tubi’s advantages:
- Largest pure on-demand FAST library
- Lower ad load than linear FAST
- Strong viewership growth trajectory
- Fox content integration
Tubi’s limitations:
- No live sports inventory
- No Amazon-style purchase data
- Library content vs. current releases
Content and Brand Safety
Tubi’s content library includes:
- Movies (catalog titles, not new releases)
- TV series (library content from major studios)
- Tubi Originals (400+ productions)
- Some news and sports content
The content skews toward entertainment rather than prestige. Think library movies and older TV series rather than the latest HBO drama. For brand safety, this is generally fine. You’re not running next to news about mass shootings or controversial documentaries.
Tubi has content partnerships with 250+ providers and recently expanded into sports (Premier League matches in certain markets) and international content (CJ ENM Korean entertainment).
Practical Campaign Considerations
Creative requirements:
- Standard CTV specs (1080p minimum)
- Multiple lengths supported (:06 through :90)
- H.264 MP4 format
- QR codes work well (viewers often have phones nearby)
What works on Tubi:
Tubi viewers have explicitly chosen to watch ads in exchange for free content. They’re not ad-averse premium subscribers grudgingly tolerating commercials. This creates a slightly more receptive environment, though you’re still competing for attention.
Creative that acknowledges everyday realities tends to resonate, messaging about real situations (car accidents, workplace injuries) rather than aspirational lifestyle content.
Frequency management: With Tubi’s AFM technology, the platform handles much of this automatically. Through programmatic buying, coordinate frequency caps across your entire CTV buy to avoid hammering the same households on Tubi AND other platforms.
Second-screen behavior: Tubi viewers often have phones in hand while watching. Strong CTAs with memorable phone numbers or clear web addresses take advantage of this. QR codes can work when viewers are engaged with their second screen.
Measuring Tubi Performance
Standard CTV measurement applies:
- Completion rates. Expect 95%+ for non-skippable inventory
- Reach and frequency. Track unique households reached
- Website visits. Pixel-based attribution for site traffic
- Search lift. Monitor branded search volume during campaigns
- Foot traffic. Available through third-party measurement for applicable businesses
Tubi’s measurement partnerships (VideoAmp, LiveRamp, Comscore) enable cross-platform analysis, so you can understand how Tubi contributes alongside other channels.
The Bottom Line
Tubi offers law firms maximum CTV reach per dollar spent. At $15-25 CPMs with 100+ million monthly users, it’s the volume play in streaming advertising.
The audience (cord-cutters, younger demographics, cost-conscious viewers) often aligns well with PI client profiles. You’re reaching people who drive, work, and don’t have family attorneys. The content environment is library movies rather than prestige TV, but for awareness-focused campaigns, that trade-off often makes sense.
Most law firms should include Tubi as part of a diversified CTV strategy rather than running it exclusively. Combine Tubi’s reach with premium inventory on Hulu or Peacock to balance volume and quality. For context on how streaming fits into a broader law firm marketing strategy, the channel mix matters more than any single platform. The platforms you don’t choose become the platforms your competitors use to reach the households you’re missing.
