Podcast Advertising Market: Podcast Ad Spend Lags Consumption, Industry Calls for Metrics Overhaul
At the IAB's Podcast Upfront, industry leaders highlighted that while podcast ad spend grew 18% to $3 billion, it lags behind consumption, which accounts for 15% of digital media time but only 2% of digital ad spend. The IAB released a new framework, 'Podcasts Continue to Evolve,' to address measurement challenges. Key issues include the shift to video podcasts, with 49% of consumers expected to watch video podcasts in 2026, and the inadequacy of download metrics. The industry is moving towards HLS streaming for better measurement, and Amazon Ads plans to integrate podcast video ad buys into its DSP. Calls were made for improved measurement and for advertisers to embrace smaller, independent shows.
Podcast advertising is a growing channel, and the call for measurement overhaul is relevant to AdTech. The announcement of Amazon Ads integrating podcast video into its DSP is a significant platform update.
