What Is WhatsApp? A Brief History
WhatsApp started as a simple alternative to expensive SMS texting. Founded by Brian Acton and Jan Koum, former Yahoo employees, the app was built on the idea of free, reliable, and ad-free communication.
Facebook (now Meta) acquired WhatsApp in 2014 for $19 billion, turning it into a global messaging leader. Today, it’s more than just texting—it supports voice and video calls, file sharing, payments, and business tools.
Why Is WhatsApp So Popular?
✅ Free & Cross-Platform – Works on Android, iOS, and desktop
✅ End-to-End Encryption – Messages stay private
✅ No Ads – Unlike many social media platforms
✅ Lightweight & Fast – Works even on slow networks
How Does WhatsApp Work?
Unlike traditional SMS, WhatsApp uses internet data (Wi-Fi or mobile data) to send messages. Here’s how it functions:
1. Registration & Setup
- Download the app from the Google Play Store or Apple App Store.
- Verify your phone number (no username needed).
- Sync contacts automatically—if they use WhatsApp, they appear in your chat list.
2. Core Features
| Feature | Description |
|---|---|
| Text Messaging | Send unlimited texts to individuals or groups (up to 1,024 members). |
| Voice & Video Calls | Make free HD-quality calls worldwide. Supports group calls (up to 32 people). |
| Media Sharing | Send photos, videos, documents (up to 2GB), and voice notes. |
| Status Updates | Share 24-hour disappearing stories (like Instagram Stories). |
| WhatsApp Web | Use WhatsApp on your computer via a browser or desktop app. |
3. Security & Privacy
WhatsApp uses end-to-end encryption (E2EE) by default, meaning only you and the recipient can read messages. However, concerns remain about:
- Metadata collection (who you talk to and when)
- Backup vulnerabilities (iCloud/Google Drive backups aren’t encrypted)
- Scams & phishing attacks (fake messages, “WhatsApp Gold” scams)
To enhance privacy, enable:
🔒 Two-Step Verification (Settings → Account)
👁️ Disappearing Messages (for auto-deleting chats)
WhatsApp vs. Competitors: How Does It Compare?
| Feature | Telegram | Signal | Facebook Messenger | |
|---|---|---|---|---|
| Encryption | E2EE (default) | E2EE (Secret Chats only) | E2EE (default) | E2EE (optional) |
| Group Size | 1,024 members | 200,000 members | 1,000 members | 250 members |
| File Sharing | Up to 2GB | Up to 2GB | Up to 100MB | Up to 25MB |
