Turner-owned cablers TNT and TBS are continuing their brand evolution under president Kevin Reilly by beefing up the networks’ marketing teams with the promotion of Jeff Gregor and the hire of Michael Engleman, who comes from NBC Universal’s Syfy and Chiller.

Gregor has been elevated to the newly-created position of chief catalyst officer for TNT and TBS, while Engleman — who was responsible for Sci Fi’s rebrand to Syfy — will join the company in early 2016 in the new post of exec vice president of entertainment marketing and brand innovation.

“We are reinventing two market-leading brands, TBS and TNT, which calls for a forward-reaching, re-imagining of our marketing organization,” said Reilly. “I have worked closely with Jeff since I joined the company, and he is one of the rare leaders who can draw on his deep brand marketing experience while reaching for new ideas and emergent methodologies. Michael will be the perfect complement to Jeff in our leadership suite – a stellar media professional with a successful track record in finding new, culturally relevant paths to the consumer.”

Engleman served as exec vice president of marketing, digital and global brand strategy for Syfy and Chiller, where he developed campaigns for “Defiance,” “12 Monkeys,” Face Off” and the pop culture phenomenon of the “Sharknado” franchise. First joining Syfy in 2008, Engleman was behind the cable net’s rebrand as it changed from Sci Fi. Before, he had served as vice president and creative director for CMT.

When he joins Turner, Engleman will oversee all branding and marketing initiatives for TNT and TBS, in addition to creating a new content marketing group to maximize opportunities presented by a fast-changing media landscape. He will be responsible for growing consumer relationships through audience development, digital and social content creation, real-time marketing and cross-platform consumer experiences.

Gregor previously served as exec vice president and chief marketing officer of both networks. In his new role, his marketing purview will be expanded; he will continue his duties and accelerate organizational change, supporting sales to monetize brand content and innovation, driving key strategic initiatives and operational efficiency and providing support to executives across all areas that interact with marketing.

While at Turner, Gregor and his team launched “Conan” as well as streaming apps for both TNT and TBS. He led marketing initiatives behind “Cougar Town,” “Rizzoli & Isles,” “Major Crimes,” “Falling Skies” and “The Last Ship,” among other series, including “The Big Bang Theory.” He also developed campaigns for the NBA, Major League Baseball and NASCAR.

Prior to TNT and TBS, which he joined in 2000, Gregor oversaw marketing for Turner Classic Movies and was the network’s general manager.

Gregor is based in Atlanta and will report to Reilly. The Los Angeles-based Engleman will report to Gregor, while working closely with Reilly.
