The 65-year-old executive has long been one of the media’s highest-paid leaders, taking home a compensation package of $51.9 million in 2024 alone—even as the company weathered layoffs and strategy turmoil. 

And earlier this year, Zaslav signed a new contract packed with more stock options that could exceed $420 million in value, with the ultimate payout influenced by whether Netflix’s $27.75-per-share cash-and-stock bid or Paramount’s hostile $30-per-share cash offer wins out.

If either deal pushes through, the package could propel Zaslav’s net worth past $1 billion, according to Bloomberg—placing him alongside a rare group of non-founder CEOs like Tim Cook, Satya Nadella, and Jamie Dimon who’ve joined the billionaire ranks.

David Zaslav missed out on being a tennis star—and vowed to never be outworked again

Zaslav began his career in corporate law before bringing his passion for strategy and negotiation to media—joining NBC in 1989 and helping launch CNBC. He rose to become president of NBCUniversal’s cable and domestic TV and new-media distribution before being tapped to lead Discovery Communications as CEO in 2006, overseeing brands like TLC and Animal Planet.

In 2022, Zaslav orchestrated the landmark Discovery-WarnerMedia merger, handing him control over powerhouse assets, including HBO, CNN, and TBS—plus Warner Bros’ vast film and TV studios.

But Zaslav maintains his real edge hasn’t been timing or luck; it’s been an almost obsessive work ethic.

He learned that lesson the hard way as a teenager chasing tennis greatness. After showing early promise, he eased up on practicing, assuming talent alone would carry him. A few months later, reality hit. His coach—professional tennis legend Althea Gibson—told him bluntly he wasn’t putting in the work. And by then, it was too late.

“By the time I was 14 years old, I was getting beat by most of the people I was used to beating,” Zaslav recalled at Boston University’s commencement in 2023. “I had already watched all the players I grew up with blow right by me. It was a painful experience. It’s painful to be outworked. I lost a little piece of my identity—but I vowed that day I would never be outworked again.”

Zaslav tells Gen Z that working hard is the most important key to success—he still wakes up at 4:45 a.m. to grind

Armed with his own experience, Zaslav warned Boston University graduates that talent is important, but just an “entry ticket.” More importantly, you have to commit yourself to working hard—and that doesn’t stop even once you reach the top.

“If you really want to realize your full potential, you cannot focus solely on what you’re good at—that’s the easy stuff,” Zaslav added. “You’ve got to put more effort toward the things you’re not good at and work at getting better at them. It’ll make a huge difference.”

Zaslav still puts his commitment to hard work into action every morning—beginning with a 4:45 a.m. wake-up call. He then hits the streets of Manhattan, often walking an hour and a half from his home on Central Park West down to his office on 19th Street—either on the phone or listening to music.

That same discipline shaped the guidance he shared with Gen Z graduates—and may even put them on a billionaire track like himself one day.

“Create your own opportunities, and even if you have to make a big change, find a way to do what you really love,” Zaslav said at Boston University, adding: “Never, never, never get outworked.”
