Marketing Attribution Models Face Scrutiny Amid TV Shift
The advertising industry is undergoing a seismic shift as marketing professionals question longstanding media measurement practices. A recent Instagram discussion ignited by an anonymous executive has cast a spotlight on the limitations of Mixed Media Models (MMMs) in evaluating the effectiveness of linear television compared to streaming platforms. As viewing habits evolve, many experts argue that current attribution models fail to accurately reflect performance across media channels.
“I don’t understand how streaming hasn’t overtaken linear in revenue. No one under the age of 45 is watching linear, so why is advertising there so important?” asked the anonymous poster on the @digital_chadvertising profile. This sparked a flurry of industry responses, many of which pointed to systemic flaws in how budget decisions are made through outdated measurement models.
Linear TV Dominates Ad Spend Despite Shifting Audiences
WPP Media’s September 2025 report revealed that despite a decline in younger audiences, linear television still commands the lion’s share of global ad budgets. Total global TV ad revenue is expected to hit $169.1 billion in 2025, with linear TV accounting for 72.6%—approximately $122 billion.
This spending imbalance is particularly striking given efficiency data. While linear television captures 67.5% of TV ad dollars, it only accounts for 54.2% of time spent. Meanwhile, Connected TV (CTV) generates 86.9% of impressions despite receiving just 32.5% of the spend. These numbers underscore a growing disconnect between audience behavior and ad investment.
Oversaturation Erodes Linear TV Campaign Impact
According to analysis from iSpot, linear television is plagued by oversaturation. The average viewer sees a linear ad 26.5 times during a campaign, compared to just 7.3 for CTV. Effectiveness peaks within the first 10 days of a linear campaign, after which additional exposures yield diminishing returns.
In contrast, CTV maintains a steady growth in efficiency throughout the campaign’s life cycle. By day 23, CTV often outperforms linear in delivering results. Leading brands are adjusting accordingly, allocating 23.7% of impressions to CTV compared to an average of 17.4% across all advertisers.
Industry-Specific Strategies Highlight Measurement Disparities
Spending patterns vary widely by sector. The travel industry leads in CTV adoption, dedicating 33.3% of impressions to the channel. Home and real estate follow at 26.1%, with pharmaceutical and medical industries at 24.1%. Entertainment brands lag, allocating only 7.6% to CTV.
These differences reflect varying levels of measurement sophistication. Industries like travel and pharma demand more precise attribution, while entertainment brands often focus on broader awareness, relying on traditional linear platforms.
Marketing Community Calls Out Model Bias
The Instagram thread exposed a troubling reality: many MMMs favor linear TV due to outdated assumptions and cost structures. “Too many MMMs support linear because it’s cheaper, even when it’s less effective,” the original poster argued. Another professional chimed in, citing live sports and news as key drivers of linear TV viewership. “If you want to watch your local team, linear is often the only option,” they noted, referencing blackout restrictions on streaming services.
Local Market Resistance Hinders Global Shifts
A global marketing executive added that many local teams resist shifting budgets away from linear TV. “We’re trying to break the linear habit, but the deals, kickbacks, and bartering make TV hard to replace,” they explained. This resistance persists despite clear inefficiencies and mounting evidence that streaming offers better value.
Streaming Surges as Platforms Expand Measurement Tools
GroupM forecasts that streaming ad spend will grow by 19.3% in 2025, while linear TV will decline by 3.4%. CTV investment is projected to double from 14% in 2023 to 28% in 2025. Netflix, for example, has expanded programmatic capabilities, allowing advertisers to purchase inventory across multiple demand-side platforms.
Advanced measurement techniques are also enhancing streaming’s appeal. Index Exchange introduced duration-based reporting in September 2025, valuing 30-second ad slots based on time spent. TVision found that streaming content captures 64% viewer attention compared to 59% for library content. Original streaming content leads with 8.5% higher attention rates than traditional programming.
Cross-Platform Solutions Bridge Gaps
New tools are enabling advertisers to better track campaign performance across linear and streaming. Campaign Manager 360’s integration with Netflix allows for unified reporting. Comscore’s Cross-Media Reach tool and VideoAmp’s partnership with Warner Bros. Discovery also offer new ways to measure reach and optimize cross-platform strategies. VideoAmp’s solution delivered a 14% digital reach lift while keeping audience overlap below 2.5%.
Demographics Complicate Spending Decisions
Despite younger audiences favoring streaming, advertisers continue to prioritize linear TV to reach older, more affluent consumers. “My 63-year-old dad has more money to spend than I do,” one marketer commented, underscoring how purchasing power influences media planning even when consumption trends suggest otherwise.
As brands attempt to balance reach, efficiency, and demographic targeting, the limitations of current models become more apparent. The industry’s reliance on broken attribution systems may be steering billions of dollars toward less effective channels, underscoring the urgent need for reform.
