This document summarizes the state of major social chat apps in late 2014, including WhatsApp, Kik, Snapchat, and Path. It discusses user growth, key features, and monetization strategies for each app. While WhatsApp remains focused solely on messaging with over 48 billion messages sent daily, Kik has doubled in size to 100 million users and allows more opportunities for advertising through shared content and partnerships with brands. Snapchat also sees increased usage but struggles to attract major advertisers due to security issues and its image. Path focuses on private sharing between close friends and generates revenue through subscriptions and in-app purchases. The document concludes by noting Facebook, Twitter, and Instagram's responses to these rising chat apps.
