# How Social Networks Automatically Create Groups Based on Time and Place > Google's patent describes a system that automatically groups social media users together based on where they are or when they are posting, allowing for instant, context-aware content sharing. - **Patent:** US 8843528 - **Original title:** Query-based user groups in social networks - **Owner:** Google LLC - **Granted:** 2014 - **Status:** Active - **Times cited:** 6 - **Field:** software, ai_ml, consumer_electronics ## What it does The system monitors the posts you make on a social network, specifically looking for location data (like a GPS coordinate) or temporal data (like a timestamp). When you create a post, the system automatically generates a query to find other users who share that same location or time context. It then creates a temporary 'social circle'—a distribution list—that includes these people, allowing you to share your post specifically with them. For example, if you post a photo at a music festival, the system identifies other users at that same venue and time, grouping them so your post reaches people who are actually there. ## What it does NOT cover - Does not cover manual group creation where a user explicitly selects friends from a list. - Does not cover content distribution based solely on pre-existing social graph connections like 'friends' or 'followers'. - Does not cover systems that rely on static user profile attributes like age, gender, or interests rather than dynamic temporal or location data. ## The clever bit The system treats a 'query' as a dynamic social filter, effectively turning a database search into a temporary, ad-hoc social network without requiring the users to know each other beforehand. ## Real-world examples 1. Location-based event feeds in apps like Instagram or Snapchat 2. Temporary group chats generated at concerts or conferences 3. Localized social discovery features ## Why it matters This patent represents a shift from social networks based on 'who you know' to networks based on 'what you are doing right now.' It was part of the era when Google attempted to compete with Facebook by integrating location-based discovery into its social ecosystem, specifically Google+. ## Frequently asked questions ### What does How Social Networks Automatically Create Groups Based on Time and Place cover?
