Apple iPhone (2007-2024): the product category that has compounded across 42+ model generations and over 2.3 billion cumulative units

The January 2007 announcement and June 2007 launch

Steve Jobs introduced the iPhone at the Macworld San Francisco keynote on January 9, 2007. The presentation has become one of the most-studied product launches in technology history. Jobs framed the iPhone as the convergence of three product categories — iPod, phone, and internet communicator — into a single device with multi-touch interaction as the binding innovation. The product launched on June 29, 2007 with AT&T exclusive carrier distribution in the US, at $499 for the 4GB model and $599 for the 8GB model.

The 2007 iPhone was technically distinctive but commercially unproven. The multi-touch display, the iPod integration, and the Safari mobile web browser were category-defining features but the device lacked 3G, copy-paste, GPS, third-party apps, and many other capabilities that competitors (BlackBerry, Windows Mobile, Palm Treo) had. Initial industry commentary was mixed; the customer reception was substantial enough to validate the bet that consumers would prefer the iPhone experience even at the high price point and feature limitations.

The 2008-2014 build: App Store, Retina, large-screen

The iPhone 3G (July 2008) added the App Store, which would become the most strategically significant addition in iPhone history. The App Store created the iOS-app developer ecosystem that has produced over the years hundreds of billions of dollars in third-party developer revenue and decisive switching-cost defense against Android. The third-party app ecosystem is arguably more important to iPhone's long-term moat than any specific hardware feature.

The iPhone 4 (June 2010) introduced the Retina display (a display resolution high enough that individual pixels are not visible at typical viewing distance) and FaceTime video calling. The iPhone 4 design was the first major industrial-design evolution from the original 2007 iPhone. The iPhone 6 and 6 Plus (September 2014) added the large-screen variant, addressing competitive pressure from Samsung Galaxy S, LG, and other Android manufacturers who had been winning customers wanting larger displays. The iPhone 6 cycle was the single best year in iPhone history by unit sales, demonstrating that screen-size preference had been a real market gap.

The 2017-2024 modern era

The iPhone X (November 2017) was the second major industrial-design evolution. Face ID replaced Touch ID; the all-screen design with the notch (a small cutout for the front-facing camera and Face ID sensor array) replaced the home button; the price point rose to $999 for the entry tier. The X-series design language has defined iPhone hardware through the 2024 iPhone 16 generation. The iPhone 11 (2019) extended the design with broader rear-camera capabilities. The iPhone 13 Pro (2021) introduced the ProMotion display (120Hz refresh rate). The iPhone 15 (September 2023) replaced Lightning with USB-C, driven in part by EU regulatory requirements.

The iPhone 16 (September 2024) was the first generation designed for Apple Intelligence. The A18 chip was specifically architected for on-device generative-AI workloads. Camera Control (a new physical button) supported Visual Intelligence features. The strategic emphasis was clear: iPhone 16 was the first iPhone whose differentiation was substantially driven by AI features rather than camera, display, or processor improvements alone. Whether Apple Intelligence will produce the upgrade-cycle acceleration Apple is projecting will play out over the iPhone 16, 17, and 18 generations.

How RGM thinks about product-category creation

When clients ask about product-category creation, the iPhone is the defining reference of the past 25 years. Three structural lessons. First, category-defining products often launch with significant feature limitations that competitors exploit but consumers tolerate because the core experience is superior — the 2007 iPhone shipped without 3G, copy-paste, GPS, third-party apps, or many BlackBerry-business features but consumers chose it anyway because multi-touch and Safari mobile web were structurally better. Second, ecosystem effects (App Store, iCloud, AirPods, Apple Watch, services) compound over many years and become more strategically important than any specific hardware feature. The third-party developer ecosystem is the most important component of iPhone's long-term moat. Third, defending category-leadership across generational technology shifts (App Store, large-screens, Face ID, USB-C, Apple Intelligence) requires sustained investment that most competitors cannot match.

The pattern is hard to copy in adjacent product categories without comparable founder-vision investment plus multi-decade compounding. Most attempted Apple-Watch-class category creations (Google Glass, Meta Smart Glasses, original Microsoft Band) have failed to reach iPhone-scale category dominance. The closest comparable case might be Apple Watch (2015 onwards) inside Apple itself, which has reached substantial scale but has not approached iPhone-class strategic importance. The iPhone remains a defining example of product-category creation that most companies should expect to study rather than to replicate.
