The iMac Revolution: From Toy to Icon
The 1998 iMac was a statement. Bright blue plastic. Transparent casing. A computer that looked like a toy. Apple sold millions of them, while critics called it a blunder. Yet, that's not the story. What started as a colorful gamble became the blueprint for every all-in-one computer that came after.
From the floating G4 on its lamp base to today's paper-thin M1, each generation broke the mold of what was considered "normal" for desktops. This 25-year evolution tells more than just a tech story. It reveals how Apple repeatedly rewrote the rules. How they went from near-bankruptcy to world domination. And why you still buy accessories today for a computer once dismissed as a toy. Even your AirPods carry the DNA of that first daring iMac.

The revolutionary start: iMac G3 (1998-2003)
The first iMac appeared in 1998 as a response to the beige boxes that dominated the market at the time. This machine, with its translucent casing and bright colors—from Bondi Blue to Tangerine—suddenly made computing accessible and even fun. The 15-inch CRT screen was integrated into the characteristic egg shape. Apple sold five million units in its first three years.
What made this computer special wasn't just its looks. The G3 eliminated outdated connections like the serial port and introduced USB as the new standard. No more floppy disk drive—a bold choice at the time. The system ran on a PowerPC G3 processor and came standard with Ethernet for internet connectivity.
The Floating Screen: iMac G4 (2002-2004)
The second generation broke completely with the previous design. A semicircular base housed all the components, while the flat LCD screen "floated" on a movable arm. Users could effortlessly tilt and rotate the display. This version came in three sizes: 15, 17, and 20 inches.
Technically, Apple switched to the more powerful PowerPC G4 processor. The machine also gained a CD/DVD burner and improved graphics capabilities. The futuristic design won awards but proved costly to produce.
Back to basics: iMac G5 (2004-2006)
With the third generation, Apple opted for a more minimalist approach. All hardware was now housed behind the flat screen—a concept that remains standard today. The white plastic casing was only 5 centimeters thick. Available in 17- and 20-inch versions, this model also introduced the iSight camera for video calling.
The PowerPC G5 chip delivered significantly more processing power. At the same time, improved cooling made the system quieter. This period also marked the transition to widescreen displays.
Intel Era Begins (2006-2007)
The switch to Intel processors in 2006 marked a turning point. Macs could now also run Windows via Boot Camp. The design remained largely the same as the G5, but performance doubled. For the first time, a 24-inch version also appeared alongside the existing 17- and 20-inch models.
Aluminum Elegance (2009-2011)
The new generation from 2009 introduced the aluminum unibody design that would remain iconic for years. LED backlighting made the screens brighter and more energy-efficient. The dimensions changed to 21.5 and 27 inches – sizes that would remain standard for a long time.
This period also saw the introduction of quad-core processors and better graphics cards. The Magic Mouse and wireless keyboard came standard.
Refinement and Retina (2012-2019)
The following years brought gradual improvements. In 2014, the 27-inch iMac arrived with a 5K Retina display—a screen so high-resolution that individual pixels were invisible. The smaller 21.5-inch version later also received a 4K display.
Fusion Drive combined an SSD with a traditional hard drive for both speed and storage capacity. Thunderbolt ports enabled lightning-fast data transfer. The design remained virtually unchanged, but performance steadily improved.
Latest Intel generation (2020)
The 2020 models received 10th-generation Intel processors and improved AMD graphics cards. The 27-inch version could be equipped with up to 128GB of RAM and 8TB of storage. The webcam was finally upgraded to 1080p—a welcome improvement for those working from home during the pandemic.
Apple also added the T2 security chip for better encryption and Hey Siri support. This ultimately proved to be Intel's swan song in the iMac line.
Silicon Revolution: M1 iMac (2021)
The latest generation, featuring Apple's proprietary M1 chip, marked a complete reboot. The 24-inch model is just 11.5 millimeters thin—thinner than many monitors. Available in seven vibrant colors, it brings back the playful character of the original G3.
The M1 chip combines the processor, graphics card, and memory into a single component. This not only delivers improved performance but also quiet operation—the smaller models are even fanless. The 4.5K Retina display offers a billion colors. Touch ID in the keyboard enables secure logins and payments.
This modern interpretation proves that the all-in-one formula is still relevant after 25 years. From colorful statement piece to business workhorse and back again – each generation reflected the zeitgeist while keeping the core idea intact.
25 Years Later: A Timeless Formula
After 25 years, the iMac formula remains surprisingly relevant. From the brightly colored plastic G3 that pulled Apple out of the doldrums to the wafer-thin M1 that returns to that playful color palette—each generation redefined what a desktop could be. The all-in-one concept , revolutionary at the time, is now the standard.
Whether you're looking for a refurbished model or the latest version, the iMac remains proof that good ideas are timeless . Even if they start out as bright blue plastic computers that no one took seriously.
