Campaign Brief
For the launch of Season 3 of Euphoria, HBO aimed to maximise awareness and sustained audience engagement across the full episode release window — driving both viewership lift and subscriber acquisition.
With Australian households increasingly managing multiple streaming subscriptions simultaneously, HBO recognised the importance of winning attention during key cultural and viewing moments. The campaign strategy therefore focused not only on building anticipation ahead of launch, but also on re-capturing audience attention immediately following each new episode release, when social conversation and viewer interest were expected to peak.
Powered by WPP ATV and Samba TV data, the campaign leveraged audience intelligence to amplify reach and frequency around these premiere moments — helping HBO stay top-of-mind throughout the season and drive stronger momentum toward episode consumption and platform consideration.
Approach
Targeting Methodology
The targeting universe was constructed using Samba TV's postcode-level viewership intelligence. Each Australian postcode was ranked by its relative over-indexing against competitor streaming platform originals, and the top 20% of postcodes by exposure density were selected as the target cohort.
These households signal a high propensity for premium long-form narrative content — making them a high-efficiency audience for an HBO drama launch. Critically, this is not a demographic or contextual proxy: it is a behavioural content affinity signal derived directly from observed household viewing history. Two sequential batches were activated across the campaign to extend and refresh reach.

Postcode Batches
Batch 1 · 13–20 Apr
488 postcodes — initial targeting cohort covering 4 episode premiere cycles. Top 20% AU postcodes ranked by overexposure to competitor SVOD originals. Activated at campaign launch, aligned to Ep 1 AEST release (13 Apr).
Batch 2 · 21 Apr – 10 May
500 postcodes — refreshed cohort applied from Ep 2 cycle onward. Built using the same over-indexing methodology against an updated competitor streaming exposure window, extending incremental reach into the remaining 3 premiere cycles.

Insights
01
Geo segments amplify impact precisely at premiere moments
Targeted postcodes consistently outperformed non-targeted on episode release days. On the Ep 1 AEST premiere (13 Apr), targeted HH reached 0.058% daily viewership vs 0.042% for the control group — a +38.8% lift on the most critical day. Across all four premiere cycles, the average peak-cycle lift held at +32.4%, confirming the segment delivered consistent incremental response with each new release.
02
Trough behaviour validates segment precision
Between episode drops, the gap inverted — targeted households reverted more sharply to rival platforms. This is not a weakness; it is direct validation that the segment correctly identified households with a strong default orientation toward competitor streaming content. The ability to pull those competitor-loyal households toward HBO at premiere moments is exactly where the targeting value is realised.
03
Consistent directional advantage across a competitive audience
Over the full 28-day period, targeted postcodes outperformed non-targeted on 14 of 28 days — concentrated around each episode release window. Given the underlying audience skews toward competitor platforms, any positive systematic lift against this cohort represents a commercially meaningful incremental outcome and a strong directional signal for future campaign planning.
Recommendations
Concentrate activation around AEST premiere windows
The lift signal is strongest in the 24–72 hours following each AEST episode release. Future campaigns should weight impression delivery heavily into premiere-day windows, with reduced spend in mid-cycle troughs where competitor-loyal audiences naturally return to rival platforms.
Expand targeting reach for future HBO titles
Apply the same competitor-streaming overexposure methodology to Batch 3+ cohorts for remaining S3 episodes and future HBO Max AU launches. The postcode ranking model is reusable and can be refreshed per title to reflect the most relevant competitor originals at time of launch.
Close the loop with subscription conversion data
Cross-reference targeted postcode viewership lift with HBO Max subscription uplift or trial activation data to compute full-funnel ROI. Matching viewership lift to downstream conversion will validate the targeting model and build the business case for scaled investment in TV geo segment activation.
