Cloud gaming is a way of playing video games in which the game runs on a server in a data centre rather than on the player's own console, PC or phone. The server renders each frame, compresses it into a video stream and sends it over the internet; the player's controller, keyboard or touch inputs travel the other way. The device in the living room or the pocket becomes little more than a screen with a network connection. The model exists to remove the two biggest barriers to modern games: expensive local hardware and long downloads.

How a streamed game reaches the screen

The loop repeats dozens of times a second. A button press leaves the device, crosses the network to the nearest server, is applied to the game, and the result is rendered by a graphics processing unit (GPU), encoded as video, packetised and sent back to be decoded and displayed. Every stage adds delay, and the sum is what players feel as lag.

Browser-based services typically ride on WebRTC, the real-time communication standard maintained by the W3C and IETF. A 2020 traffic study of Google Stadia by Marc Carrascosa and Boris Bellalta found video and audio carried as RTP packets, usually over UDP, with RTCP reporting reception quality back to the server. Video used the VP9 or H.264 codecs, chosen at the start of a session, and audio used Opus at about 120 kbps. Across ten games at 1080p, average downlink traffic ranged from about 1.95 Mbps to 37.7 Mbps, while uplink traffic, the inputs, stayed between 0.21 Mbps and 1.1 Mbps.

Bandwidth and latency set the limits. Nvidia's GeForce NOW requires 15 Mbps for 720p, 25 Mbps for 1080p at 60 frames per second and 45 Mbps for 4K at 120 frames per second, and asks for less than 80 milliseconds of network latency to an Nvidia data centre, according to its system requirements page. Microsoft caps Xbox Cloud Gaming at 30 Mbps for selected 1440p titles on its top tier and 12 Mbps at 1080p on cheaper tiers. Google warned that Stadia could use up to 20GB of data per hour at 4K and 60 frames per second, according to PCGamesN.

Because distance adds delay, operators place GPU servers in regional or edge data centres close to population centres. Microsoft's service runs on Xbox Series X hardware installed in Azure facilities, an infrastructure advantage tied to its position as a hyperscaler. Nvidia's newest tier uses RTX 5080-class GPUs from its Blackwell generation, the same chip family that data centre buyers deploy for AI inference, and Nvidia claims click-to-pixel latency below 30 milliseconds at 1080p.

Business models

Four models dominate. Catalogue subscriptions bundle streaming with a library: Xbox Game Pass and PlayStation Plus Premium. Bring-your-own-library services such as GeForce NOW stream games the player has already bought on stores like Steam. Bundled perks add games to a broader subscription, as Netflix and Amazon do. And free tiers fund access through queues, session caps and, increasingly, advertising.

From OnLive to the living room

OnLive, founded by Steve Perlman, was unveiled at the Game Developers Conference in March 2009 and launched in the United States on June 17, 2010. It collapsed in August 2012, when it laid off staff, amid reports that its servers had peaked at only about 1,400 concurrent users. Sony bought Gaikai, a rival, for $380 million in July 2012, and in April 2015 acquired OnLive's assets before that service closed on April 30.

Gaikai's technology became PlayStation Now, announced on January 7, 2014, opened in beta on July 31, 2014 and released fully in North America on January 13, 2015. It reached 3.2 million members by March 2021 and was folded into the PlayStation Plus Premium tier in mid-2022. Nvidia started its Grid beta in 2013, branded it GeForce NOW on its Shield devices in 2015 and launched the service publicly on February 4, 2020.

Google announced Stadia on March 19, 2019 and launched it on November 19, 2019 in 14 countries, with a Pro tier at $9.99 a month. Microsoft revealed Project xCloud in October 2018 and launched it for Game Pass Ultimate members on September 15, 2020. Amazon announced Luna on September 24, 2020 and opened it to all US customers on March 1, 2022.

Where advertising enters

For marketers, cloud gaming matters because it converts the console into another streaming screen with a free, ad-funded tier attached. Nvidia began showing up to two minutes of video ads before each one-hour session on GeForce NOW's free tier on March 5, 2024, saying the change would "reduce average wait times for free users over time", according to TweakTown.

Microsoft followed. In October 2025 it began internally testing free Xbox Cloud Gaming with ads, with about two minutes of preroll, one-hour sessions and five hours a month. On July 23, 2026, Xbox Wire extended the test to Xbox Insiders and published five advertising principles, including "We do not interrupt the flow of gameplay."

Television makers sell the surrounding inventory. Samsung Ads offers a Gaming Hub masthead unit, a 624 by 352 pixel static or autoplay tile on 2022 to 2024 Samsung TVs, according to its DSP documentation. At Gamescom 2025, PHYND, a free ad-supported cloud gaming service, signed a distribution deal with Samsung Gaming Hub, according to Adweek. On mobile, Samsung's cloud platform expanded to the UK and Germany in August 2025, with Moloco running user acquisition campaigns.

The advertising link predates these tiers. Google's Trial Run Ads of December 2015 streamed the real game from a server for up to 60 seconds, an early cloud-rendered alternative to HTML5 playables. Measurement remains thin: the IAB Gaming Measurement Framework of June 2025 noted that console and PC offer fewer readily available metrics than mobile, where formats such as Roblox's rewarded video report completion rates above 90%.

Latency, caps and the Stadia problem

Physics remains the first objection. Fast competitive games are sensitive to delays that video streaming tolerates easily, and performance degrades on congested Wi-Fi or mobile networks. Data use collides with broadband caps in markets such as the United States, where two hours a day at Google's 4K figure would use about 1.2 terabytes a month.

Ownership is the second. Google announced Stadia's closure on September 29, 2022, with Phil Harrison, its head, saying it "hasn't gained the traction with users that we expected", according to 9to5Google. The service went offline on January 18, 2023; Google refunded hardware and game purchases. Amazon showed a similar fragility in April 2026, when Luna stopped selling individual games and third-party subscriptions from EA, Ubisoft and GOG and ended support for purchased titles on June 10, according to VGC.

Content access is a third. Activision Blizzard, Bethesda and 2K pulled games from GeForce NOW within weeks of its February 2020 launch, forcing Nvidia to an opt-in publisher model. Apple's 2020 App Store rule requiring each cloud game to be listed individually pushed Microsoft into the browser.

Capacity is a fourth. Nvidia imposed a 100-hour monthly cap on paid tiers from January 2026, with extra 15-hour blocks at $2.99 or $5.99, and said only 6% of users average more than three hours a day, according to TechSpot.

Competition authorities treated cloud gaming as the decisive market in Microsoft's $68.7 billion purchase of Activision Blizzard. The UK's Competition and Markets Authority (CMA) blocked the deal on April 26, 2023, estimating Microsoft's share of UK cloud gaming at 60% to 70%, according to TechCrunch. The European Commission cleared it on May 15, 2023 with a 10-year free streaming licence for Activision games. The CMA then approved a restructured deal on October 13, 2023, under which Ubisoft took Activision's cloud streaming rights outside the European Economic Area (EEA) for 15 years. Martin Coleman, chair of the CMA panel, called cloud gaming "an important new way for gamers to access games." Critics argue the remedies did little for prices: Game Pass Ultimate rose 50% to $29.99 a month in October 2025, despite Microsoft's 2023 assurance that prices would not rise as a result of the merger.

Not the same as

Game streaming in the Twitch or YouTube sense means broadcasting gameplay for an audience to watch; the viewer cannot control the game. Remote play streams a game from the player's own console or PC to another device in the home, with no data centre involved, although the PlayStation Portal added cloud streaming on November 5, 2025. A subscription catalogue such as Game Pass is a pricing model; most of its games are downloaded and run locally, with cloud play as one access route.

Recent developments

Xbox Cloud Gaming left beta on October 1, 2025, and extended streaming to all Game Pass tiers. In February 2026 GeForce NOW arrived on Amazon Fire TV sticks at up to 1080p and 60 frames per second. Amazon launched a Masters of the Universe party game exclusively on Luna on June 5, 2026, included with Prime. Netflix, which now competes for daily attention with apps built on formats such as the microdrama, described its "cloud-first gaming strategy" on January 21, 2026; co-chief executive Greg Peters said about one-third of members could play on TV. Ubisoft began streaming Activision titles through Ubisoft+ Premium via GeForce NOW on December 4, 2025. As of October 2026, Microsoft's ad-supported tier remains in testing, part of a gaming business that also cut about 9,000 jobs company-wide in July 2025.

Summary

Who. Platform holders and infrastructure firms run the services: Microsoft (Xbox Cloud Gaming), Nvidia (GeForce NOW), Sony (PlayStation Plus Premium), Amazon (Luna), Netflix and Samsung, with Ubisoft holding Activision's cloud rights outside the EEA. Advertisers buy preroll in free tiers and TV-level inventory around the services, while regulators such as the CMA and European Commission police competition.

What. A delivery method in which a game runs on a remote GPU server, frames are encoded and streamed as video, typically over WebRTC and UDP, and player inputs travel back, needing roughly 15 Mbps to 45 Mbps and low network latency.

When. OnLive launched commercially in June 2010; Sony bought Gaikai in 2012 and launched PlayStation Now in 2014-2015; Stadia, Xbox and Luna arrived between 2019 and 2022; Stadia closed in January 2023; ad-funded free tiers spread from March 2024, with Microsoft testing its own from October 2025.

Where. In regional data centres close to players, streamed to smart TVs, streaming sticks, browsers, phones, handhelds and older consoles.

Why. It removes the cost of local hardware and downloads, extends console games to any screen and gives platforms a route to ad-funded play, but latency, data caps, capacity costs and the fragility of games tied to a service remain contested.
