A Brief History of Internal Communication
Before diving deeper, let’s take a step back. Workplace communication has evolved dramatically over the decades:
- Pre-1990s: Communication relied heavily on face-to-face meetings, phone calls, memos, and printed newsletters.
- 1990s – Early 2000s: Email became the dominant form of communication. Platforms like Outlook and Lotus Notes ruled.
- Mid-2000s: Instant messaging tools (like Skype for Business, AOL Instant Messenger) entered offices.
- 2010s: Collaboration platforms like Slack (2013) and Microsoft Teams (2017) transformed how organizations communicate.
- 2020 and Beyond: The COVID-19 pandemic accelerated remote work, making video conferencing tools like Zoom indispensable. AI, automation, and hybrid platforms are now shaping the future.
Today, communication tools are not just about sending messages—they’re about building culture, managing projects, and aligning entire organizations.
