CTV vs Cable TV Advertising for Law Firms

Cable TV has been a staple of law firm advertising for decades. CTV is where viewers are heading. Understanding the differences helps you allocate budget effectively.

The Audience Reality

Cable's audience has declined significantly:

• Cable viewing dropped 39% since 2021
• Cord-cutting accelerates every year
• Streaming now accounts for 44.8% of TV viewing

Cable still has audience—but it's smaller and older than it was. 90% of U.S. households now use CTV devices.

Targeting Comparison

The gap is significant. Cable reaches "people watching HGTV at 7pm." CTV reaches "auto loan holders in specific zip codes with workers' comp research behavior."

Cost Comparison

Cable Costs

Market	Monthly Cost (typical buy)
Small DMA	$8,000-15,000
Mid DMA	$15,000-30,000
Major DMA	$25,000-50,000
Top DMA	$40,000-80,000+

CPMs typically range $10-25 depending on network and daypart.

CTV Costs

Market	Monthly Budget
Small DMA	$15,000-25,000
Mid DMA	$30,000-50,000
Major DMA	$50,000-80,000
Top DMA	$75,000-150,000+

CPMs typically range $35-50 for quality inventory.

Effective CPM Comparison

Raw CPM doesn't tell the full story:

Channel	CPM	Target Relevance	Effective CPM
Cable	$18	8%	$225
CTV	$42	25%	$168

CTV's higher CPM can deliver lower effective cost per qualified impression.

Measurement Comparison

Cable Measurement

• Estimated ratings (not actual counts)
• GRP calculations
• Phone ring correlation
• No household-level tracking
• Limited attribution capability

CTV Measurement

• Actual impression counts
• 90%+ household match rates
• Verified website visits
• Conversion attribution
• Multi-touch tracking

CTV accounted for 38% of impressions but 63% of attributable conversions—measurability that cable can't match.

Completion and Attention

Cable Viewing

• Background viewing common
• Channel surfing during ads
• DVR skipping prevalent
• Lower ad engagement overall

CTV Viewing

• 94-96% completion rates
• Non-skippable (typically)
• 56% attention rate
• Active viewing environment

CTV viewers watch your full message. Cable viewers may have wandered to the kitchen.

When Cable Still Makes Sense

Live Sports

Sports streaming exists, but traditional cable still carries significant sports inventory. If your market is sports-focused, cable sports maintains value.

News Programming

Local news on cable still reaches older demographics. For firms targeting 55+, cable news remains relevant.

Tight Budgets

Cable's lower minimums can work for budget-constrained testing. But results will be less measurable.

Existing Relationships

Long-term cable rep relationships can provide value in placement and pricing. These relationships have value. But shouldn't override strategic considerations.

When CTV Outperforms

Growth Objectives

Building awareness with measurement requires CTV. You can't prove cable ROI with confidence.

Targeting Precision

Reaching specific behavioral audiences requires CTV. Cable offers demographics; CTV offers behaviors.

Competitive Markets

Standing out requires reaching the right people, not just reaching people. CTV targeting provides edge.

Accountability Requirements

If you need to prove ROI to partners or investors, CTV delivers the attribution cable lacks.

Younger Demographics

Viewers under 50 are increasingly streaming-first. Cable misses significant portions of this audience.

The Hybrid Approach

Many firms run both:

Scenario	Cable %	CTV %
Traditional market, older target	40-50%	50-60%
Growth market, mixed demographics	25-35%	65-75%
Competitive market, accountability focus	15-25%	75-85%
Streaming-heavy market	10-20%	80-90%

The trend favors CTV, but cable still has role for specific objectives.

Transition Considerations

If you're currently cable-heavy:

Don't cut abruptly: Gradual shift protects momentum

Test CTV first: Prove performance before full transition

Compare fairly: Give CTV 90 days, proper attribution

Track both: During transition, measure what each contributes

See Transitioning from Broadcast to CTV for detailed migration guidance.

The Bottom Line

For most PI firms seeking growth with accountability, CTV should be primary, cable supplemental.
