2004–2009: Creation and early history in 2025 Roblox was created in 2004 by co-founders and software engineers
David Baszucki and Erik Cassel. Before the creation of the platform, both Baszucki and Cassel worked for Knowledge Revolution, a company that specialized in creating educational and physics simulation software. After Knowledge Revolution was acquired by
MSC Software, the two left the company and Baszucki began investing in earlier social media sites like
Friendster. Around this time, Baszucki came up with the idea of a physics sandbox with creation tools and a social networking aspect. Baszucki and Cassel began development on Roblox shortly afterwards, modeled after Baszucki's vision, and also created the
Roblox Corporation. Early in its development, Roblox was known as "DynaBlocks". It was determined early on in development that the two would design Roblox to rely entirely on user-generated content, only providing the tools necessary for people to develop games, as well as the server hosting later in development. with Roblox Studio being made available that same year. Games that were made by the community early in the platform's history included paintball games, haunted houses and model trains that players could ride. In 2008, the Roblox Corporation stopped actively creating its own games to demonstrate the platform's capabilities, becoming entirely reliant on user-created games. They would subsequently add two additional tiers: Turbo Builders Club and Outrageous Builders Club.
2010–2015: Early growth Roblox's growth continued throughout 2010 and the following years. By August 2011, Roblox had about 6.8 million active users monthly, becoming the second-most popular kids entertainment site. Its profits also continued to increase, with the platform's profit that year up 75% from 2010; in June 2011, the company held a fundraiser that raised over $4 million. By January 2014, the platform's monthly player count had increased 10 to 12 million monthly players, although a majority of those players did not have registered accounts and instead played as "guests". By this point in the platform's history, several games had been played million of times. One of the most successful creators on the platform at the time was Luke Weber, known on Roblox as "Stickmasterluke", who had a following of over ten million plays across all of his games combined. It was attended by over 1,000 people. although users were not able to use Roblox Studio. After completing development on the iOS version, Roblox began looking into releasing a version for
Android devices, as well as video game consoles. The version for Android was released on July 16, 2014. A version of Roblox for
Xbox One was announced in September 2015 and released on November 20. This version initially only released with selection of 15 games chosen by Roblox staff, due to concerns regarding
Entertainment Software Rating Board standards. A system that allowed users to publish their games on the platform was later released, based on an approval process. From 2013 to 2014, Roblox released several updates to its development tools, adding new features. which initially only allowed payouts of up to $500.
2016–2020: Accelerated growth and COVID-19 In the latter half of the 2010s, Roblox began to rapidly grow in popularity. By December 2016, the platform had about 30 million monthly active users, a number that had increased to 90 million by April 2019. Between March and April, Roblox reported having over 120 million monthly active players, which by that point the company said included over half of all kids in the United States that were under the age of 16. By this point, over 20 games had been played more than one billion times, and at least 5,000 had been played more than one million times. In light of the platform's newfound popularity and use during lockdowns, Roblox introduced a new "Party Place" system, which were specific spaces that players could use to arrange meetups and events, such as
virtual concerts. In June of that year, the company also released a dedicated app for
Windows 10. Efforts were also made towards making Roblox more accessible, with automatic
machine translation being added to in-game chat in 2020, initially supporting 9 languages. and was given permission to release in the region on December 3, 2020. During this time period, several features from the platform were removed. In 2016, Roblox discontinued its secondary currency, "Tickets", making Robux the platform's only currency. It was removed due to the company believing newer players would get confused by the presence of two separate currencies. That same year, Roblox discontinued its official player
forums for an undisclosed reason. Additionally, in 2019, Roblox released Roblox Premium, which replaced its previous Builders Club memberships. In March 2021, the Roblox Corporation
went public, and became valued at $45 billion. At the same time, a port of Roblox to the
PlayStation 4 were announced, and later released on October 10. It is playable on the
PlayStation 5 via
backward compatibility. In 2021, Roblox made it to where games on the platform are referred to as "experiences" following the platform's involvement in the
Epic Games v. Apple lawsuit. In June of that year, Roblox was sued by the
National Music Publishers' Association (NMPA), alleging that the platform allowed users to upload copyrighted music without obtaining proper licensing, and made children believe that
pirating music was acceptable. The lawsuit was dropped by September, ending with the Roblox Corporation and the NMPA forming a collaboration to establish a framework for future publisher partnerships. After being given permission in late 2020, Roblox released in China in July 2021. was published and operated by Tencent, and was heavily restricted due to
China's regulations on video games. LuoBu failed to grow to substantially throughout its history, and was unable to generate much profit. Roblox's business model throughout this time has continued to be based around creating a metaverse, and attempting to increase the platform's appeal. In 2021, Baszucki further detailed the company's vision for Roblox to become a metaverse, highlighting "eight different characteristics" that the platform would strive to accommodate for. He also discussed the
Ready Player One and
Ready Player Two books as being inspirations for the company's ideas. for users over the age of 13 that had their age
verified through ID. Voice chat was then followed by facial animations based on the real-world motion tracking of the players face, which was announced in 2022 and released in 2023. In March 2024, two
generative artificial intelligence tools that were added to Roblox Studio in an effort to speed up content creation. These tools were for automatic avatar customization and texture generation, the former being able to automatically convert three-dimensional body meshes into live-animated avatars and the latter creating textures of objects based on a
text-to-image model. Also announced in 2022 were
age ratings for games, Initially, the highest rating that games could be given was 13+, although in June 2023, a 17+ rating was introduced that would permit games to feature more
graphic violence, romantic themes and alcohol usage. Similarly, in November 2024, Roblox revamped its
parental controls system, adding new safety measures for users under the age of 13, such as
screen time and whether or not the child can exchange private messages with other users and allowing parents to create separate accounts to control their child's account.
2026–present Starting with certain countries in December 2025 and globally in January 2026, Roblox made age verification mandatory to communicate on the platform in any capacity. A $12 million settlement served as a model for platform accountability, where funds were allocated for youth programs and law enforcement. Non-encrypted messaging for user safety was also part of the agreement terms. In June 2026, the platform will introduce more age-based restrictions by dividing user accounts into different tiers of Roblox: "Roblox Kids" (available to users under the age of 9), "Roblox Select" (for users 9 to 15), and standard Roblox (for users 16 and over). If a user does not verify their age, they are restricted to only playing games with an age rating of 9+ or lower. Age estimation or verification will also become mandatory to publish a game. A port of Roblox for the PlayStation 5 was released on April 14, 2026. ==Community and culture==
