Local TV Broadcasting Leader in the U.S. Optimizes Revenue with Sigma


The fourth largest independent TV station owner in the U.S. shares news and entertainment across 60 television stations in 42 markets. To understand audience engagement and measure both national and local media group performance, the company ingests and analyzes billions of rows of operational and TV ratings data from sources like Nielsen and Comscore.

However, the company’s legacy data analytics architecture required constant administrative oversight, basic queries took hours to run, and it could take 3 months to add a new data source – all of which stifled data exploration, significantly delayed insight discovery, and led to missed revenue opportunities. Furthermore:

  • The legacy architecture was couldn’t handle the volume of data necessary for 2 reports that were key to driving revenue: a year-to-date data by market analysis and a year-over-year sweeps rating comparison. The BI team tried to build these reports in Tableau for 2 months before abandoning the project.
  • Scale and performance limitations made it impossible to effectively analyze data across sources and filters could take an hour or more to load.
  • The company also lacked a way for the BI team to collaborate on analytics with their line of business counterparts or quickly share new insights with TV station leaders.

With Sigma, the BI team built a live dashboard with ratings and revenue data that now informs critical business decisions. The content team monitors and optimizes audience engagement. The sales team drives revenue by leveraging data to sell advertising placements based on a mix of programming, demographics, and market.

Sigma was purpose-built for Snowflake and cloud data warehouses. The BI team now has direct access to live data in Snowflake, ensuring that everyone is always looking at the same current data.
