Apple's next era: why John Ternus?

An in-depth explanation of why Apple chose John Ternus, an internal engineer, after Tim Cook, looking together at the changes in the Jobs and Cook eras and the next growth tasks.

Updated Apr 21, 2026

Apple chose insider John Ternus as its next CEO. John Ternus is the Senior Vice President of hardware engineering. He has long been mentioned as a strong successor to Tim Cook. Tim Cook joined Apple in 1998. Then in 2011, after Steve Jobs stepped down, he became CEO. At that time, many people worried about Apple without Jobs. But Apple grew very big in the Cook era. During this period, Apple released new products like Apple Watch, AirPods, and Vision Pro. John Ternus led the development of iPad and AirPods during this time. He also has been in charge of developing iPhone, Mac, and Apple Watch. This appointment is seen as a sign that Apple has started preparing for its next era.

Key points

Why did Apple put a 'product engineer' after an operations expert?

This news is interesting not just because the CEO changed. Who comes after Tim Cook is a clue that shows what kind of company Apple wants to become in the future. After Cook, who was strong in supply chains and service expansion, Apple chose John Ternus, an engineer who has made products inside the company for more than 20 years.

Simply put, it is like this. If Apple in the Jobs era was 'a company that throws out products the world had never seen,' Apple in the Cook era was 'a company that grows those products into a huge ecosystem and a system that makes money.' But now a new turning point is coming, with AI, semiconductors, and spatial computing. So people are saying maybe Apple wants to put product-centered judgment forward again.

John Ternus is not an outside star manager. He is someone who has handled core products like iPad, AirPods, Mac, iPhone, and Apple Watch inside the company for a long time. In a company like Apple, where secrecy is strong and hardware, software, and chips are tightly and complexly connected, choosing someone who knows the inside structure through real experience may be more convincing than bringing in a flashy person from outside.

ℹ️In one line

Apple looks like it is preparing for the 'era of product engineering' after the 'era of operations.'

The choice of John Ternus looks like a decision that carries expectations for the next product turning point, more than simple stability.

Sales

Why can the hardware chief become a CEO candidate — the money involved is just too big

This is based on Apple FY2024. If you look at the numbers, you can quickly see why the hardware chief is not just a simple tech leader.

iPhone (68%)
Mac (10%)
iPad (9%)
Wearables·Home·Accessories (13%)
Meaning

This role matters because it is connected not to just a 'pretty product,' but to Apple's whole money flow.

Apple's hardware engineering chief is not just someone who picks parts. This role is responsible for whether the product actually works well like the iPhone's heat, the Mac's performance, the Apple Watch's battery, and the AirPods' fit. On the outside, design comes first, but when the customer pays money, in the end, quality decides the game.

More important is the scope. Based on FY2024, iPhone sales alone are 2,012hundred million dollars. If you add Mac, iPad, and wearables, the sales base connected to the hardware organization is overwhelming. So the hardware chief is a 'technician' and at the same time the person responsible for a huge business.

💡It is easy if you understand it like this

It is similar to a picture where, at a car company, the person who oversees the engine, body, and driving performance all becomes the next CEO.

History

From Jobs's Apple to Cook's Apple, and now to Ternus's Apple

The leadership change at Apple did not break all at once. It continued as the way the company grew changed.

1

Stage 1: 1998~2011, the time when Jobs and Cook built the foundation together

Tim Cook joined Apple in 1998 and strengthened its supply chain and operations. In front, Jobs led product innovation with things like the iMac, iPod, and iPhone. Behind the scenes, Cook made it possible to sell those products in large volumes and in a stable way.

2

Stage 2: 2011, the test of 'Apple without Jobs' begins

When Jobs stepped down and Cook became CEO, many people thought Apple's innovation would end too. That was because people had seen Apple for too long as something tied to Jobs's personal sense and style.

3

Stage 3: 2014~2024, Cook grew Apple into a bigger system

With Apple Watch, AirPods, services, payments, and even the shift to in-house chips, Apple became both a product company and a platform company. It was not just about selling one iPhone and stopping there. Apple built a structure where the subscriptions and ecosystem after that also make money.

4

Stage 4: 2026~, now the question is the 'next product transition period'

Apple choosing John Ternus can be read to mean that the next era's test is not operations but products. In a market shaken by AI and spatial computing, the key question has become whether Apple can create another strong hardware experience.

Growth

What Tim Cook grew was not one iPhone but the 'Apple ecosystem'

Service revenue is the number that best shows how Apple moved from a hardware company to a platform company.

Context

If the Jobs era was 'one big innovation,' the Cook era was 'a system of recurring revenue'

When people think of Apple in the Steve Jobs era, they usually first remember symbolic moments like the iPhone. But the real change in the Tim Cook era was in something a little less flashy. It built an installed base, meaning a huge group of users already using Apple devices, and on top of that it grew recurring revenue from things like the App Store, iCloud, Apple Music, and payments.

If we compare this in a familiar way, it is like not stopping after one big sale of a popular phone, but building a structure that also connects mobile fees, content, memberships, and payments. So Apple's Cook era became both an 'innovative company' and at the same time a 'mega platform company,' and John Ternus now has the task of proving product innovation again on top of this huge system.

ℹ️Key numbers

Service revenue grew from a single-digit billion-dollar scale in the early 2010s to about 96.2 billion dollars in 2024.

This number is the proof that 'Apple is no longer only a hardware company.'

Products

Apple Watch, AirPods, Vision Pro, did they really become a 'second iPhone'?

Product groupNumbers and status confirmed in researchKey point
iPhoneAbout $200.6 billion in FY2023 revenueIt is still the main pillar of Apple's revenue structure.
Wearables·Home·AccessoriesAbout $39.8 billion in FY2023 revenueApple Watch and AirPods contributed a lot, but it is still smaller than the iPhone division alone.
Vision ProApple does not disclose separate revenue, so it is still hard to compare with numbers.It has big symbolic meaning, but at this stage it is safer to see it as a niche new product.
Evaluation

It was not the same kind of success — the report card for Apple Watch, AirPods, and Vision Pro

ProductWhat kind of success was it?What are the limits?
Apple WatchAn ecosystem-style success that expanded health, fitness, and the wearables marketIt is not a single revenue pillar that carries the whole company like the iPhone.
AirPodsA consumer product-style success with strong mass appeal, repeat purchases, and market shareRather than being an independent platform, it works more as glue for the iPhone ecosystem.
Vision ProAn experimental platform attempt with strong symbolic value in technologyThe price is high and mass adoption is still at an early stage, so it is far from being 'the second iPhone.'
Outlook

What does Apple under John Ternus need to prove first?

Now one question remains. Is John Ternus a great product manager, or a leader who can open a new era? The homework Tim Cook left is clear. The iPhone is still huge, but the market is mature, and AI is trying to change the next interface after the phone.

So the first test of the Ternus era will likely be 'how Apple turns AI into a hardware experience.' It could be smart glasses, a next Vision device, or a completely different personal device. What matters here is not a tech demo, but whether Apple can make a product in its own way that is expensive but still makes people want to buy it, and uses complex technology but is easy to use.

There is also a reason this news is interesting from Korea. Samsung is pushing foldables and the device ecosystem, Google is pushing AI, and Meta is pushing smart glasses. Apple's choice of the next CEO is connected in the end to the answer to 'where is the next battlefield?' So this appointment is not just news about changing a person. It is closer to a signpost for the direction of the IT world for the next 10 years.

⚠️Checkpoints in the Turners era

Can AI be tied together not as a software feature but as a hardware experience?

Can the spatial computing strategy after Vision Pro be expanded into mass-market products?

Can it reduce dependence on the iPhone while still keeping Apple's premium profit structure?
