Sony introduced its first clock radios in the mid-1960s; the Dream Machine brand was introduced later. The devices allowed users to wake up to a radio broadcast instead of a conventional alarm sound, as many people found the loud mechanical alarm made by traditional alarm clocks disturbing. The use of direct-read digital display as opposed to a traditional clock dial gave the design a modernistic feel, which reflected the modernist or Space Age design trends of the period. It is not certain if Sony truly invented the concept of digital radio clock with Dream Machine, but it was among the early commercially successful clock-radio product lines. The earliest models were intended only for the Japanese domestic market, and since Sony has never published an official product chronicle, information on these early models has been scarce online and often in Japanese only, sourced from outdated marketing material and old catalogues. By the late 1960s, Sony began to export these machines and soon they become an international hit. It was a popular choice of holiday gift by early 1970s worldwide. It was one of the first widely adopted home digital appliances. By the mid-1980s many rival products existed, although the Dream Machine line was considered premium due to its stylish design, high quality components, simplicity, ease of use, and good sound quality for its radio. Many original working examples survive to this day with minimal maintenance. For a short time in the late 2000s, the radio clock market experienced a resurgence, because of several new models including iPod / iPhone 30 pin docks and CD players. By the early 2010s, Sony stopped manufacturing new clocks under the "Dream Machine" name. At the time of discontinuation, the name was used for over forty years. The "Snooze" button featured in all digital alarm clock, was stylized as "Dream Bar" on a Dream Machine. In Japan, Dream Machine's Alarm function is called "Ohayo" mode which literally means "Good Morning" in English. For certain markets and eras, Sony would use other commercial names for their radio clock products, such as DIGIMATIC (UK/EU), or Digital 24 (US/North America), however the actual design would be identical or similar to those branded as Dream Machine. The manufacturing of Dream Machine is an early example of outsourcing. The vast majority of Dream Machines were assembled outside of Japan, in either Hong Kong or Malaysia, and later models were mostly made in China.

While the basic idea of the Dream Machine is simply a combination of an analog radio and a digital clock, display technology evolved with time, from mechanical split-flap display at introduction, to VFD (1970s - 80s), and eventually to more energy efficient LED / OLED (primarily 1990s onward). Certain later models were also capable of docking digital players such as iPod and iPhone, serving as an amplifier for the external device. Other than a handful of 1960s models which used synchronized motor driven flip page, most Dream Machine was powered by the use of specialized microcontroller optimized for digital clocks. With the use of one single microcontroller it is possible to keep time, drive display segments and switch the radio on and off. Dream Machine's microcontroller uses AC mains power (at 50/60 Hz) as reference signal instead of a crystal oscillator. While this design gives remarkable accuracy, clock pace is not ensured outside of its intended market. Some models (like Japan or AEP model) feature a 50/60 Hz switch, but for models without such a switch, the circuit shall need to be modified if intended to use in an area with a different mains frequency. An optional 6F22 backup battery (later model may use CR2032) can be installed, to prevent a probable power failure event (i.e. a blackout) from resetting the clock. The vast majority of Dream Machine uses traditional string-pulled tuning for its radio, despite the prevalence of digital phase-locked loop tuning. This is likely to facilitate more intuitive continuous blind tuning for a user lying in bed.

One of the first clock radios, released in 1968. The clock displays the time by a mechanical flip mechanism. It has an alarm and also has an FM and AM radio.

Released around 1978. Cube body clock radio in various colors, bearing "Digicube" branding. The C11W is FM/AM while the C11L is FM, AM, and LW.

Introduced in 1981. The C12, nicknamed "Tomato" in Japan, has a cube shape and bright red as color option while C16, nicknamed "Coffee", featured a rectangular design. Both models featured a VFD display, driven by a CMOS microcontroller.
