MediaCo Bolsters Sigma Platform With High-Profile Personality-Driven Shows.

Sigma Audio Networks is expanding its national footprint with the addition of two prominent multicultural audio brands, further building out its personality-driven programming strategy.

The network, powered by MediaCo, has reached agreements to bring Don Cheto and “Hot 97 Mornings with Mero” onto its platform, enhancing its ability to deliver scaled audio content across both broadcast and digital channels.

Under the deals, Sigma becomes the exclusive national home for Don Cheto, taking on syndication and national ad sales responsibilities. The move positions one of Spanish-language radio’s most recognizable personalities for broader distribution, supported by centralized monetization and platform reach.

At the same time, “Hot 97 Mornings with Mero” will move into national syndication, extending beyond its flagship on “Hot 97” WQHT in New York. The program, which blends music, humor, and culturally resonant conversation, has quickly gained traction among both Hispanic and Black audiences.

“This expansion reflects the growing demand for culturally relevant, personality-led audio at scale,” said Brian Fisher, Chief Revenue Officer, MediaCo. “By bringing leading franchises like Don Cheto and HOT 97 Mornings with Mero onto the Sigma platform, we are strengthening our ability to deliver both reach and impact for advertisers.”

Elisa Torres, President & CEO, Sigma Audio Networks, added. “Both Don Cheto and Hot 97 Mornings with Mero represent the type of content that drives audience engagement today—authentic, culturally connected, and built around strong personalities and teams. Through Sigma, we are scaling that content nationally across broadcast and digital platforms.” The latest deals advance Sigma’s broader strategy to reach 150 million multicultural consumers across the U.S., combining heritage brands, original programming, and multi-platform delivery into a unified national audio offering.
