Linda Yaccarino made waves when she announced she was stepping down as the CEO of X on July 9, 2025, but her career didn’t start in the tech space.

From decades at Turner Broadcasting, to climbing the ladder at NBCUniversal, to becoming chief executive of X, Yaccarino has climbed the advertising ladder.

Here’s a quick breakdown on her path to — and now away from — X.

Yaccarino is a graduate of Pennsylvania State University.

According to her LinkedIn, Yaccarino was a liberal arts student who studied telecommunications between 1981 and 1985.

She had an early internship at NBCU, where she eventually worked decades later.

Yaccarino told Salesforce in an interview that she arrived on her first day as a “bright cheery new intern,” but soon learned that the company didn’t have a record of her in its system and she ended up on the media planning team.

“That’s where the love affair was born,” Yaccarino said of her interest in working in the media industry.

Yaccarino spent nearly 20 years at Turner Broadcasting System.

An NBCU “boomerang” return hire, Yaccarino once again worked at NBCU after leaving Turner.

She began her second chapter at the company as its president of cable entertainment and digital advertising sales.

She eventually became the company’s advertising chief.

At NBCU, Yaccarino was key to the company’s push into digital streaming.

Musk made the announcement on what was still Twitter at the time: “@LindaYacc will focus primarily on business operations, while I focus on product design & new technology.”

He called her “smart, fair and reasonable” in a separate post after some conservatives on Twitter had criticized her ties to the World Economic Forum, an annual event for executives and influential figures in Davos, Switzerland.

Yaccarino also worked with President Donald Trump and President Joe Biden’s administrations.

In 2021, she worked with the Biden administration on an educational COVID-19 ad campaign.

Musk renamed Twitter to X one month into Yaccarino’s tenure, and she led the company during a tumultuous time.

She oversaw the platform during an advertiser exodus, working to convince advertisers to return. Advertisers began to return under her leadership, but Musk’s changes to X — including loosening content moderation — continue to pose potential challenges.

Yaccarino announced she’s stepping down as CEO of X on July 9, 2025.

After two incredible years, I’ve decided to step down as CEO of 𝕏.

When @elonmusk and I first spoke of his vision for X, I knew it would be the opportunity of a lifetime to carry out the extraordinary mission of this company. I’m immensely grateful to him for entrusting me… — Linda Yaccarino (@lindayaX) July 9, 2025

Yaccarino made the announcement in a post on X: “I’m incredibly proud of the X team – the historic business turn around we have accomplished together has been nothing short of remarkable.”

She hasn’t indicated what she plans to do next.
