What Is OTT and What Is CTV?

A CTV is any internet-connected television or device that enables streaming. This includes:
Smart TVs

Why CTV Advertising Is Easier Than Traditional TV
One of the biggest benefits for marketers — especially small and local businesses — is how simple and accessible CTV advertising is compared with traditional TV.
Traditional TV Advertising Challenges
High minimum budgets (often $20k+)
Fixed time slots
Limited targeting (age, gender, DMA)
No real-time reporting
No precise attribution
CTV Advertising Advantages
Runs on any budget (as low as $500–$2,000)
Targeting based on real data:
Household income
ZIP code
In-market buyers
Interests & behaviors
Delivery across all major apps
Reports include:
Impressions
Completion rates
Frequency
Household reach
Store visits
Website conversions
CTV democratizes access to TV-level advertising.
Why CTV & OTT Are Beneficial for Small & Local Businesses
Small businesses historically could not advertise on TV due to cost.
Streaming has changed this forever.
Why small/local businesses love CTV advertising:
You can target only your ZIP codes or radius
You pay only for impressions — not showtimes
Your ads appear on premium content like:
ESPN
Discovery
AMC
Food Network
Local news streams
It builds trust because customers associate streaming with “real TV”
Reporting is transparent
What this means for SMBs
Higher trust than social media ads
More consistent attention than mobile ads
More cost-efficient than traditional TV
Measurable results
