Dolby Laboratories, Inc. (often shortened to Dolby Labs and known simply as Dolby) is a British-American technology corporation specializing in audio noise reduction, audio encoding/compression, spatial audio, and HDR imaging. Dolby licenses its technologies to consumer electronics manufacturers.

Google LLC ( , GOO-gəl) is an American-based multinational corporation and technology company focusing on online advertising, search engine technology, cloud computing, computer software, quantum computing, e-commerce, consumer electronics, and artificial intelligence (AI). It has been referred to as "the most powerful company in the world" and is one of the world's most valuable brands due to its market dominance, data collection, and technological advantages in the field of AI. Google's parent company, Alphabet Inc., is one of the five Big Tech companies, alongside Amazon, Apple, Meta, and Microsoft.

Google was founded on September 4, 1998, by American computer scientists Larry Page and Sergey Brin while they were PhD students at Stanford University in California. Together, they own about 14% of its publicly listed shares and control 56% of its stockholder voting power through super-voting stock. The company went public via an initial public offering (IPO) in 2004. In 2015, Google was reorganized as a wholly owned subsidiary of Alphabet Inc. Google is Alphabet's largest subsidiary and is a holding company for Alphabet's internet properties and interests. Sundar Pichai was appointed CEO of Google on October 24, 2015, replacing Larry Page, who became the CEO of Alphabet. On December 3, 2019, Pichai also became the CEO of Alphabet.

The company has since rapidly grown to offer a multitude of products and services beyond Google Search, many of which hold dominant market positions. These products address a wide range of use cases, including email (Gmail), navigation and mapping (Waze, Maps and Earth), cloud computing (Cloud), web navigation (Chrome), video sharing (YouTube), productivity (Workspace), operating systems (Android), cloud storage (Drive), language translation (Translate), photo storage (Photos), videotelephony (Meet), smart home (Nest), smartphones (Pixel), wearable technology (Pixel Watch and Fitbit), music streaming (YouTube Music), video on demand (YouTube TV), AI (Google Assistant and Gemini), machine learning APIs (TensorFlow), AI chips (TPU), and more. Discontinued Google products include gaming (Stadia), Glass, Google+, Reader, Play Music, Nexus, Hangouts, and Inbox by Gmail. Google's other ventures outside of internet services and consumer electronics include quantum computing (Sycamore), self-driving cars (Waymo, formerly the Google Self-Driving Car Project), smart cities (Sidewalk Labs), and transformer models (Google DeepMind).

Google Search and YouTube are the two most-visited websites worldwide followed by Facebook and Twitter (now known as X). Google is also the largest search engine, mapping and navigation application, email provider, office suite, online video platform, photo and cloud storage provider, mobile operating system, web browser, machine learning framework, and AI virtual assistant provider in the world as measured by market share. On the list of most valuable brands, Google is ranked second by Forbes and fourth by Interbrand. It has received significant criticism involving issues such as privacy concerns, tax avoidance, censorship, search neutrality, antitrust and abuse of its monopoly position. On August 5, 2024, D.C. Circuit Court Judge Amit P. Mehta ruled that Google held an illegal monopoly over Internet search.

The inch (symbol: in or ″) is a unit of length in the British Imperial and the United States customary systems of measurement. It is equal to ⁠1/36⁠ yard or ⁠1/12⁠ of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb.

Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.

A laser differs from other sources of light in that it emits light that is coherent. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as optical communication, laser cutting, and lithography. It also allows a laser beam to stay narrow over great distances (collimation), a feature used in applications such as laser pointers, lidar, and free-space optical communication. Lasers can also have high temporal coherence, which permits them to emit light with a very narrow frequency spectrum. Temporal coherence can also be used to produce ultrashort pulses of light with a broad spectrum but durations as short as an attosecond.

Lasers are used in optical disc drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic and free-space optical communications, semiconductor chip manufacturing (photolithography, etching), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and in laser lighting displays for entertainment. Semiconductor lasers in the blue to near-UV have also been used in place of light-emitting diodes (LEDs) to excite fluorescence as a white light source; this permits a much smaller emitting area due to the much greater radiance of a laser and avoids the droop suffered by LEDs; such devices are already used in some car headlamps.

A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers. A virtual retinal display, or retinal projector, is a projector that projects an image directly on the retina instead of using an external projection screen.

The most common type of projector used today is called a video projector. Video projectors are digital replacements for earlier types of projectors such as slide projectors and overhead projectors. These earlier types of projectors were mostly replaced with digital video projectors throughout the 1990s and early 2000s, but old analog projectors are still used at some places. The newest types of projectors are handheld projectors that use lasers or LEDs to project images.

Movie theaters used a type of projector called a movie projector, nowadays mostly replaced with digital cinema video projectors.

Xiaomi Corporation (; Chinese: 小米集团), commonly known as Xiaomi, is a Chinese designer and manufacturer of consumer electronics and related software, home appliances, automobiles and household hardware, with headquarters in Beijing, China. It is the second-largest manufacturer of smartphones in the world, behind Samsung, most of which run on the Xiaomi HyperOS (former MIUI) operating system. The company is ranked 338th and is the youngest company on the Fortune Global 500.

Xiaomi was founded in 2010 in Beijing by Lei Jun along with six associates. Lei had founded Kingsoft as well as Joyo.com, the latter of which he sold to Amazon for $75 million in 2004. In August 2011, Xiaomi released its first smartphone and, by 2014, it had the largest market share of smartphones sold in China. Initially the company only sold its products online; however, it later opened brick and mortar stores. By 2015, it was developing a wide range of consumer electronics. In 2020, the company sold 149.4 million smartphones and its MIUI (now Xiaomi HyperOS) mobile operating system has over 500 million monthly active users. As of August 2024, Xiaomi is the second-largest seller of smartphones worldwide, with a market share of about 12%, according to Counterpoint. Its presence led some people to call Xiaomi the "Apple of China". It has come up with its own range of wearable items. It also is a major manufacturer of appliances including televisions, flashlights, unmanned aerial vehicles, and air purifiers using its Internet of things and Xiaomi Smart Home product ecosystems.

Xiaomi keeps its prices close to its manufacturing costs and bill of materials costs by keeping most of its products in the market for 18 months, longer than most smartphone companies. The company also uses inventory optimization and flash sales to keep its inventory low.
