Catherine Sullivan is upending the TV upfronts. As the video marketplace becomes increasingly complex to navigate because of new ad formats, various audience-targeting initiatives and the growth in content platforms, Sullivan is looking to create a more strategic, relevant and integrated approach by bringing the TV networks and publishers directly to clients.

This year, Sullivan, who joined Omnicom in 2016, oversaw the holding company’s first upfronts presentation. The three-day event gathered 20 TV networks, publishers and platforms—including ABC, NBC Universal, Fox, Facebook and Condé Nast—to present customized advertising opportunities to Omnicom’s clients. Sullivan’s philosophy is that instead of looking at ad spending in silos, there should be a sales environment that reflects the way marketers actually buy media.

Sullivan, a 30-year veteran of network sales who has spent time at both ABC and NBC, already has a clear understanding of how the other side works. It’s this insight into the sell side that has positioned her to reimagine how the video-buying process can operate for marketers.
