Nuñez will transition to an advisory role after helping build CBS' global distribution business for over two decades.
Armando Nuñez is passing the baton at the ViacomCBS Global Distribution Group as Dan Cohen becomes the new head of the studio's division in June.
Nuñez, who previously transformed CBS Studios International into a worldwide distribution leader before the merger of the network with Viacom, will shift into an advisory role.
"Thanks to Armando's exceptional leadership, the critical work to unify our global licensing and distribution operations is complete, and the team is moving forward with a comprehensive strategy for the future," said ViacomCBS president and CEO Bob Bakish in a statement Wednesday.
The shake-up follows Nuñez in fall 2019 being named chairman, global distribution group and chief content licensing officer for ViacomCBS as Viacom and CBS completed its merger. He was charged then with leading the integration of CBS and Paramount's global licensing/distribution teams.
"When Bob asked me to lead this group post-merger, part of the plan was that I would transition from day-to-day leadership to an advisory role once the two teams were integrated and a future strategy was set," said Nuñez in his own statement.
"Working side by side with Dan, that process has gone faster than expected and is now complete. We are well-positioned wherever this rapidly evolving media landscape takes us, and I can't think of anyone better to lead us forward than Dan," he added.
For his part, Cohen in a statement said he and Nuñez had laid down a solid foundation for the global division: "We've built a world-class team and have a treasure trove of quality content that will propel this division forward. I couldn't be more excited to lead this group into the future."
In his new role as president of the ViacomCBS Global Distribution Group, Cohen will oversee global sales of ViacomCBS product that airs on the CBS Television Network, The CW, CBS All Access and Showtime, as well as programming from Paramount Pictures, Paramount Television, Paramount Players, Paramount Animation, CBS Television Studios, CBS News and the Viacom brands.
He will also look to monetize ViacomCBS' library of film and television titles and run worldwide home entertainment for the company. Cohen most recently served as president, global content licensing for ViacomCBS since the merger in December 2019.
Previously, Cohen served as president of worldwide home entertainment & television distribution for Paramount Pictures, which he joined in 2017.
Nuñez joined CBS Broadcast International as president in July 1999. In January 2000, following the merger of CBS Television and King World Productions, he added the title of executive vp of CBS Enterprises. He was named president of CBS Studios International (formerly CBS Paramount International Television) in August 2004 following the merger with Paramount International Television.
Before joining CBS, Nuñez served as president of Universal Television. From 1994-97, he was president of New World International Television Distribution and before that, executive vp international sales at Viacom Enterprises.
