Altspacevr

In 2017 it was acquired by Microsoft and became part of the Mixed Reality division (alongside notable products like HoloLens and HoloLens 2) within the Cloud and AI group. Some elements of the platform appear in Microsoft Mesh.

The platform largely consisted of user-generated spaces called "worlds", which could be visited by other users. Individuals could gather, talk, collaborate, and be co-present in small to large groups.

The platform was regularly home to a wide variety of live virtual events from VR church and LGBTQI+ meetups to large business conferences and magic shows.

In January 2023 it was announced on the AltspaceVR Homepage that the service would be shutting down on March 10, 2023.

AltspaceVR was organised in spaces called "worlds", which could be found and accessed via a floating menu or via in-world "teleporters". Some large worlds, such as the "Campfire", were built and maintained by official developers as places for users to meet and interact. As of May 2022, AltVR removed all developer-maintained worlds.

Altspace's internal menus included a list of "featured" user-defined worlds and a real-time list of the most "popular" worlds, arranged by the number of users currently visiting each world. Other menus listed current and planned "events", which took place inside official or user-generated worlds.

Notable events that took place within AltspaceVR included:

• a virtual fashion show for 2020 Paris Fashion week
• a red carpet premiere of Baba Yaga with celebrities Jennifer Hudson and Daisy Ridley was held in a VR world produced by Big Rock Creative.
• In 2020 AltspaceVR was home to BRCvr, a recognized universe of the Burning Man multiverse.
• In 2021 AltspaceVR was home to Thursday Night Club Premier
• In 2022 AltspaceVR hosted the book launch of new sci-fi short stories book with introduction by Douglas Rushkoff and "The Summoned" story by Eva Pascoe with live feed from authors by Zoom into Altspace event venue

AltspaceVR supported several VR headsets:

• SteamVR devices (HTC Vive, Valve Index...)
• Oculus Rift/Rift-S via Oculus Store
• Oculus Quest/Quest 2 (as a standalone app, or via Oculus Link)
• Windows Mixed Reality devices
• Samsung Gear VR (discontinued mid-2020)

The platform was available as a traditional desktop application for Mac and Windows, and had a non-VR Android app until 2019.
