What is Linear Television (TV) Advertising?

Linear TV advertising is the traditional method of broadcasting television advertisements aired during commercial breaks within scheduled programming on cable or satellite TV channels. 

The term “linear TV” comes from content delivery’s sequential, or “linear,” nature. 

In contrast to streaming services, where viewers choose content at their leisure, linear formats schedule and broadcast programs in a set order, requiring viewers to tune in at specific times.

What is the difference between non-linear and linear TV?

Linear TV delivers content at a scheduled time, while non-linear TV removes this limitation. Viewers can decide when and what to watch.

Streaming networks like Netflix, Hulu, and others are non-linear TV services, as viewers can choose where and when to watch.

Linear TV vs Over-The-Top (OTT) & Connected TV (CTV) Advertising

Linear TV advertising follows a traditional approach with scheduled ad slots on cable or satellite channels, targeting a broad audience. OTT and CTV advertising use internet-based platforms for precise audience engagement and targeting.

Linear TV vs Addressable TV Advertising

Linear TV advertising reaches a wide audience with the same ad across all screens, relying on broad demographic targeting based on the program’s viewership. Addressable TV advertising delivers different ads to different households watching the same program.

How Does Linear TV Advertising Work?

Linear TV advertising works by placing commercials during breaks in TV programming.

The process typically works like this:

  1. Target Audience Analysis: Advertisers identify the demographic they want to reach, considering factors like age, gender, interests, and viewing habits.
  2. Programming Selection: Based on the target audience, advertisers select TV programs that align with their viewers’ preferences.
  3. Time Slot Booking: Advertisers book time slots for their commercials, choosing when their target audience will most likely be watching.
  4. Cost Negotiation: Advertisers negotiate costs with TV networks or cable providers. Costs vary based on factors like the show’s popularity, time slot, and audience reach.
  5. Ad Scheduling and Placement: Ads are scheduled and placed during commercial breaks within the chosen programs.
  6. Performance Tracking: Advertisers track the performance of their TV ads using metrics like ratings, viewer feedback, and indirect measures like increased website traffic or sales during the ad campaign.

Once an ad plays on linear TV, advertisers may adjust their strategies based on performance data, viewer trends, and changes in programming schedules.

The Benefits of Linear TV Advertising

Linear TV benefits include: 

1. Broad Reach

Linear TV still captures a large audience, particularly among older demographics. Linear TV ad impressions reached more viewers aged 55 and older than younger audiences. Viewers aged 65 and older dedicate an average of 4 hours and 58 minutes daily to watching linear TV, in stark contrast to the 25-34 age group, watching only 1 hour and 12 minutes daily.

2. Air Time or Channel Segmentation

While linear TV doesn’t offer the same level of sophisticated audience targeting as CTV/OTT platforms, it does provide the ability to target audiences based on specific channels or broadcast times. This is most successful if you know that your ideal customers tend to watch a particular show at a specific time.

3. Live Event Sponsorship

Advertising during live events, like sports or award shows, can reach captive, engaged audiences. Despite streaming services vying for a piece of the live sports market, technical challenges like increased latency mean that linear TV is still the go-to for broadcasting these events.


Is Linear TV advertising still relevant?

“As the media landscape evolves rapidly, linear TV will maintain its relevance and influence in 2024. While it is a tried & true tactic for awareness-driven campaigns, due to the broad reach of a diverse demographic, the 2024 Election and the Olympics will further boost ad spending for this year, keeping linear in the advertising game.”

The Problem with Traditional TV Advertising/Linear TV Advertising

Linear TV still functions as an effective mass reach strategy, but there are challenges that advertisers are forced to address along with limitations in the buying model.

1. Media Waste is Inevitable

Linear TV’s strength in mass reach often becomes a double-edged sword. While advantageous for brand visibility, the broad reach leads to media waste, where a significant portion of the advertising budget is spent on reaching viewers outside the brand’s target audience. 

Advertising efforts and expenditures may not contribute effectively to the brand’s specific marketing objectives.

2. Fragmentation is a Challenge

Today, TV content is not just confined to the traditional television set. Viewers access their favorite shows and movies across various devices like smartphones, tablets, laptops, and streaming devices like Chromecast. 

Audience fragmentation means linear TV advertisers have difficulty capturing a significant, unified viewership.

3. Measurement is Difficult

In the era of linear TV, ratings have been the cornerstone of measuring a show’s popularity and, by extension, the potential reach of advertisements. However, as media consumption habits evolve, these ratings lose their once-critical relevance.

Each upfront season, which sets the stage for advertising contracts, highlights this shift, with ratings no longer providing the comprehensive insight they once did. 

Nielsen traditionally measures linear TV viewership by distributing devices to around 100,000 viewers in 41,000 households and then extrapolates this data to estimate nationwide viewership percentages.

Unlike linear, digital platforms offer many actionable insights, allowing advertisers to track user engagement, click-through rates, conversions, and other metrics in real-time.

4. Viewership is Declining (Steeply)

As viewers shift to Connected TV, linear TV viewership is declining. Linear TV decreased from 51.4% in June 2023 and a more substantial year-over-year drop from 56.0% in July 2022.

Projections suggest that by 2025, US adults will spend over an hour more per day on digital video compared to traditional TV.

Connected TV (CTV) as a Solution to Linear’s Shortcomings

Connected TV (CTV) is a viable solution to address linear TV’s shortcomings, offering a blend of high viewer engagement and sophisticated targeting capabilities.

1. High Engagement with Unskippable Ads

Being mostly unskippable, CTV ads boast video completion rates often exceeding 90%. The advertiser’s entire message is more likely to be seen and heard.

2. Advanced Targeting Capabilities

CTV goes beyond the broad demographic targeting of traditional TV, utilizing detailed demographic, geographic, and behavioral data. 

3. Combating Fragmentation

CTV addresses linear TV’s fragmentation problem by providing a consolidated platform for inventory across a wide range of content categories. By partnering with companies like KORTX, advertisers can access multiple inventory sources through a single platform.

 4. Measurable and Optimizable

Advertisers can access impression-level reporting, monitor video completion rates, and check viewability metrics. This allows for real-time, mid-campaign adjustments to optimize performance.

How does CTV advertising complement or provide a solution to linear TV’s shortcomings?

“CTV’s ability to incorporate precise audience targeting and trackable actions make it the perfect complement or substitute for linear TV. If a brand wants extensive reach and awareness, linear can be a great tactic. Pair it with CTV, and you have a plan that reaches people across devices and pushes users further down the marketing funnel. CTV is also a great alternative to linear if a brand seeks a highly targeted and cost-effective tactic that still reaches users on well-known, quality publishers.”
