Isentia data powers the Guardian’s analysis of the marriage equality media debate

Summary: The Guardian used Isentia media monitoring data to reveal that the No campaign’s lead spokesperson received more media mentions than all three leading Yes campaigners combined, exposing a significant imbalance in how Australia’s marriage equality debate was being covered.

Published in September 2017, during the Australian Marriage Law Postal Survey, this Guardian Australia article drew on Isentia media monitoring data to quantify the imbalance in how the marriage equality debate was being reported. The analysis showed that the Australian Christian Lobby’s Lyle Shelton had accumulated more media mentions across news outlets than the three leading Yes campaign figures — Alex Greenwich, Tiernan Brady, and Sally Rugg combined.

The finding became one of the most widely cited data points of the entire postal survey period, sparking broader discussion about the media’s role in amplifying particular voices during democratic debates. For Isentia, the story demonstrated the power of media intelligence data to inform public discourse, not just corporate strategy, and cemented the company’s position as Australia’s authoritative source of media measurement.
