25 Iconic Apple WWDC Moments From Steve Jobs to Tim Cook

Apple’s Worldwide Developers Conference (WWDC) is transitioning leadership as CEO Tim Cook prepares to host his final event on June 8, 2026, before handing the reins to John Ternus. According to TechRadar, the conference has evolved from a secretive 1983 debut of the Apple Lisa into a massive global showcase for innovations like the 2023 Vision Pro reveal.

Who is taking over from Tim Cook?

John Ternus is set to succeed Tim Cook as the leader of Apple. Cook is hosting his final WWDC on June 8, 2026, marking the end of an era for the company’s public-facing developer events, according to TechRadar.

How has the WWDC evolved since 1983?

The event began in 1983 as a secretive gathering that provided insiders with a first look at the Apple Lisa. It remained a relatively niche event until 1997, when Steve Jobs returned to Apple and transformed the conference into the software and technology showcase it is today.

By WWDC 2000, the scale of the event had grown significantly. Steve Jobs used the platform to demo the upcoming Mac OS X, which later launched in public beta in September 2000. TechRadar notes that 3,500 developers attended the 2000 event, making it the highest-attended WWDC in the company’s history at that time.

The conference later shifted toward showcasing high-end hardware and spatial computing. In 2023, Tim Cook revealed the Vision Pro, continuing the tradition of using the developer conference to launch products that redefine the company’s hardware trajectory.

What were the most critical hardware shifts at WWDC?

Two major architectural pivots define the history of the conference. In 2003, Steve Jobs introduced the Power Mac G5. The machine was known as the cheese grater and represented one of the final desktop workhorses Apple developed in partnership with IBM.

Just two years later, Apple fundamentally changed its computing strategy. At WWDC 2005, the company announced it would ditch PowerPC processors and move to Intel chips, a move that sent shockwaves through the computing industry, according to TechRadar.

The contrast between these two events highlights a rapid shift in Apple’s supply chain and engineering philosophy. The transition from the IBM-partnered G5 to Intel chips within a two-year window demonstrates the company’s willingness to abandon existing architectures to pursue better performance.

Why does the history of WWDC matter for developers?

WWDC serves as the primary bridge between Apple’s internal engineering and the external developer community. The shift from the secretive 1983 event to the open, high-attendance format of the 2000s allowed thousands of developers to align their software with new operating systems like Mac OS X.

This relationship has evolved from simple software updates to the introduction of entirely new computing paradigms, such as the spatial computing environment introduced with the Vision Pro in 2023. As leadership moves from Tim Cook to John Ternus on June 8, 2026, the industry will watch to see if the conference maintains its role as the primary catalyst for Apple’s technical pivots.
