Case Study: ITV achieves seamless, risk-free modernisation of £1.7B ad revenue systems with New Relic

The UK’s Biggest Commercial Broadcaster Modernises Key Ad Revenue Systems with New Relic

ITV, the UK’s largest commercial broadcaster and maker of shows like Coronation Street and Downton Abbey, needed to modernise its critical ad sales and revenue systems that generate £1.7 billion annually. The ad stack was a complex, Java-based monolith spread across regional on‑premises systems, and migrating to AWS and a microservices architecture risked disrupting advertiser-facing workflows and revenue.

By instrumenting both the legacy and new stacks with New Relic (APM, Infrastructure, Browser, Insights, Synthetics) and adopting an incremental migration approach, ITV gained a single pane of glass for real‑time visibility, dashboards and alerting. This enabled faster diagnosis and fewer incidents during cutovers, accelerated the move to microservices and AWS, and avoided major disruptions to ad sales while creating a scalable, cloud‑native ad platform.
