PlayStation (Japanese: プレイステーション, Hepburn: Pureisutēshon, officially abbreviated as PS) is a video gaming brand that consists of five home video game consoles, two handhelds, a media center, and a smartphone, as well as an online service and multiple magazines. The brand is produced by Sony Interactive Entertainment, a division of Sony.

The first PlayStation console was released in Japan in December 1994, and worldwide the following year. The original console in the series was the first console of any type to ship over 100 million units, doing so in under a decade. Its successor, the PlayStation 2, was released in 2000; it is the best-selling home console to date, having reached over 155 million units sold by the end of 2012. Sony's next console, the PlayStation 3, was released in 2006, selling over 87.4 million units by March 2017. Sony's next console, the PlayStation 4, was released in 2013, selling a million units within a day, becoming the fastest selling console in history. The latest console in the series, the PlayStation 5, was released in 2020 and sold 10 million units in its first 249 days, unseating its predecessor as the fastest-selling PlayStation console to-date. The main series of controllers utilized by the PlayStation series is the DualShock, a line of vibration-feedback gamepads that sold 28 million units by June 2008.

The first handheld console in the series, the PlayStation Portable (PSP), sold a total of 80 million units worldwide by November 2013. Its successor, the PlayStation Vita (PSVita), which launched in Japan in December 2011 and in most other major territories in February 2012, sold over four million units by January 2013. PlayStation TV is a microconsole and a non-portable variant of the PlayStation Vita handheld game console. Other hardware released as part of the PlayStation series includes the PSX, a digital video recorder which was integrated with the PlayStation and PlayStation 2, though it was short-lived due to its high price and was never released outside Japan, as well as a Bravia television set which has an integrated PlayStation 2.

The PlayStation Network is an online service with about 110 million registered users (as of June 2013) and over 103 million active users monthly. (as of December 2019) It comprises an online virtual market, the PlayStation Store, which allows the purchase and download of games and various forms of multimedia, a subscription-based online service known as PlayStation Plus and a social gaming networking service called PlayStation Home, which had over 41 million users worldwide at the time of its closure in March 2015. PlayStation Mobile (formerly PlayStation Suite) is a software framework that provides PlayStation content on mobile devices. Version 1.xx supports both PlayStation Vita, PlayStation TV and certain devices that run the Android operating system, whereas version 2.00 released in 2014 only targeted PlayStation Vita and PlayStation TV. Content set to be released under the framework consist of only original PlayStation games currently.

Seventh generation PlayStation products also use the XrossMediaBar, which is an Technology & Engineering Emmy Award–winning graphical user interface. A touch screen-based user interface called LiveArea was launched for the PlayStation Vita, which integrates social networking elements into the interface. Additionally, the PlayStation 2 and PlayStation 3 consoles also featured support for Linux-based operating systems; Linux for PlayStation 2 and OtherOS respectively, though this has since been discontinued. The series has also been known for its numerous marketing campaigns, the latest of which being the "Greatness Awaits" and eventually, "Play Has No Limits" commercials in the United States.

The series also has a strong line-up of first-party games due to PlayStation Studios, a group of many studios owned by Sony Interactive Entertainment that exclusively developed them for PlayStation consoles. In addition, the series features various budget re-releases of games by Sony with different names for each region; these include the Greatest Hits, Platinum, Essentials, and The Best selection of games.

Wireless communication (or just wireless, when the context allows) is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth, or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, such as light and magnetic or electric fields, or the use of sound.

The term wireless has been used twice in communications history, with slightly different meanings. It was initially used from about 1890 for the first radio transmitting and receiving technology, as in wireless telegraphy, until the new word radio replaced it around 1920. Radio sets in the UK and the English-speaking world that were not portable continued to be referred to as wireless sets into the 1960s. The term wireless was revived in the 1980s and 1990s mainly to distinguish digital devices that communicate without wires, such as the examples listed in the previous paragraph, from those that require wires or cables. This became its primary usage in the 2000s, due to the advent of technologies such as mobile broadband, Wi-Fi, and Bluetooth.

Wireless operations permit services, such as mobile and interplanetary communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g. radio transmitters and receivers, remote controls, etc.) that use some form of energy (e.g. radio waves and acoustic energy) to transfer information without the use of wires. Information is transferred in this manner over both short and long distances.
