Originally intended to replace the built-in browser in the viewer, the Shared Media Texture soon became so much more.
Shared Media Textures, dubbed by users as Media Prims, allows a user to add a web page directly onto the face of a prim. It was introduced along with the Viewer2, the second version of the official viewer. The Media Prim can be modified in many ways and allows for a complete customization of how it is displayed or interacted with. Early adopters quickly turned this technology from a simple web browser into a fully interactive media experience.
One of the biggest things were the in-world TV sets. Crafty people found ways to isolate the video from streaming sites like Youtube and Dailymotion and display them directly on media prims. These TV sets quickly became fully fledged home entertainment systems, with the ability to switch the land radio stream to either a vast predefined list, or your own URL and some could even play specific songs on demand.
Business developers could use these Media Prims to create in-world overhead projectors to display graphs and slides during international business meetings, without ever having to leave their offices. Schools used similar methods for distance learning.
We at The Torch use Media Prims all over Second Life, as a way to display our latest articles in-world to our readers from Second Life. Most of the in-world newcomer academies we have worked with use them to display schedules and information on upcoming events without ever having to upload new textures. Clubs use them to display the profile picture of their current entertainers.
Because the way they completely transformed how we interact with prims and textures, Shared Media Textures has earned a spot on our list of technologies that revolutionized Second Life.
