The Master System is an 8-bit third-generation home video game console manufactured by Sega. It was originally a remodeled export version of the Sega Mark III, the third iteration of the SG-1000 series of consoles, which was released in Japan in 1985 and featured enhanced graphical capabilities over its predecessors. The Master System launched in North America in 1986, followed by Europe in 1987, and then in Brazil and Korea in 1989. A Japanese version of the Master System was also launched in 1987, which features a few enhancements over the export models (and by proxy the original Mark III): a built-in FM audio chip, a rapid-fire switch, and a dedicated port for the 3D glasses. The Master System II, a cheaper model, was released in 1990 in North America, Australasia and Europe.
The PlayStation 4 (PS4) is a home video game console developed by Sony Interactive Entertainment. Announced as the successor to the PlayStation 3 in February 2013, it was launched on November 15, 2013, in North America, November 29, 2013 in Europe, South America and Australia, and on February 22, 2014 in Japan. A console of the eighth generation, it competes with Microsoft's Xbox One and Nintendo's Wii U and Switch.
The PlayStation Vita (PS Vita, or Vita) is a handheld game console developed and marketed by Sony Interactive Entertainment. It was first released in Japan on December 17, 2011, and in North America, Europe, and other international territories beginning on February 22, 2012. The console is the successor to the PlayStation Portable, and a part of the PlayStation brand of gaming devices; as part of the eighth generation of video game consoles, it primarily competed with the Nintendo 3DS.
The Nintendo 3DS is a handheld game console produced by Nintendo. It was announced in March 2010 and unveiled at E3 2010 as the successor to the Nintendo DS. The system features backward compatibility with Nintendo DS video games. As an eighth-generation console, its primary competitor was Sony's PlayStation Vita.
The PSX (PlayStation X) is a Sony digital video recorder with a fully integrated PlayStation 2 home video game console. It was released in Japan on December 13, 2003. Since it was designed to be a general-purpose consumer video device, it was marketed by the main Sony Corporation instead of Sony Computer Entertainment and does not carry the usual PlayStation branding. Initial sales were strong, with the console selling 100,000 units during its first week, thus selling out. Its high cost, however, resulted in poor sales later on, prompting Sony to cancel plans to release the PSX outside Japan. After the price had been lowered in September 2004, sales increased again.

The Katana Set 2 was basically a prototype PowerVR2 ARC graphics card that slipped into a Pentium 2 based PC. It was used mostly for tech demo's early in the dreamcast development.
Oculus began shipping Development Kit 2 (DK2) in July 2014. This is a small refinement of the "Crystal Cove" prototype, featuring several key improvements over the first development kit, such as having a higher-resolution (960×1080 per eye) low-persistence OLED display, higher refresh rate of 75 Hz, positional tracking, a detachable cable, and the omission of the need for the external control box.
A teardown of DK2 revealed that it incorporates a modified Samsung Galaxy Note 3 smartphone display, including the front panel from the device itself.
In February 2015, Oculus announced that over 100,000 DK2 units had been shipped up until that point.
Two months after being formed as a company, Palmer's Oculus VR launched a Kickstarter crowdfunding campaign on August 1, 2012 for their virtual reality headset, named the Rift. The main purpose of the Kickstarter was to get an Oculus Rift prototype—now referred to as DK1 (Development Kit 1)—into the hands of developers to begin integration of the device into their games. The DK1 was given as a reward to backers who pledged $300 or more on Kickstarter, and was later sold publicly for $300 on their website. These kits sold at a rate of 4–5 per minute for the first day, before slowing down throughout the week.
The Rift DK1 was released on March 29, 2013, and uses a 7-inch (18 cm) screen with a significantly lower pixel switching time than the original prototype, reducing latency and motion blur when turning one's head quickly. The pixel fill is also better, reducing the screen door effect and making individual pixels less noticeable. The LCD is brighter and the color depth is 24 bits per pixel.
