1. The First Email Was Sent in 1971
The very first email in history was sent in 1971 by computer engineer Ray Tomlinson. At the time, he was working on a project called ARPANET, the forerunner of the modern Internet. His goal was to find a way to send messages between two computers on a network. Using a program called SNDMSG, he successfully transmitted a message from one machine to another that was literally sitting next to it.
This was also the moment he introduced the now-famous "@" symbol to separate the user name from the host name in an email address (e.g., arun@example.com). It became a standard across the world. Interestingly, the content of the first email wasn’t anything meaningful—Tomlinson later said it was likely just a string of random letters.
Despite its simplicity, that small step revolutionized global communication. Today, over 300 billion emails are sent every day across the world. What started as a test message between two machines laid the foundation for personal and professional digital communication.
Email has become indispensable in both personal and professional life. It has paved the way for faster and more efficient communication across the globe.
2. The First Computer Mouse Was Made of Wood
The first computer mouse was invented by Douglas Engelbart in 1964, and surprisingly, it was made out of wood. This early version of the mouse was a simple, rectangular device with two wheels on the bottom, used to track the movement on the screen. Engelbart, who worked at the Stanford Research Institute, designed the mouse as part of his vision to create a system of interacting with computers using multiple devices.
The wood-based mouse was quite bulky and not as sleek as today's models, but it marked the beginning of an era of user-friendly computer interaction.
Engelbart's invention was initially met with skepticism, but it eventually led to the development of the modern mouse, which has become one of the most widely used input devices in the world. The wooden mouse is now on display at the Computer History Museum in Mountain View, California.
3. Google Handles Over 8.5 Billion Searches Per Day
Google is the undisputed leader in the search engine industry, handling over 8.5 billion searches every day. This staggering number reflects not only the massive popularity of Google but also its dominance in the digital age.
Founded in 1998 by Larry Page and Sergey Brin, Google started as a university project and quickly grew into the world’s most used search engine, capturing a market share of over 90%.
With its sophisticated AI-driven systems and billions of indexed web pages, Google is able to provide highly personalized search results to users. Today, Google Search powers everything from homework help to business research in a fraction of a second.
6. Facebook’s Blue Color Has a Reason
Facebook's blue color scheme is not just a random design choice; it was selected for a very specific reason. Mark Zuckerberg, the founder of Facebook, is red-green colorblind, which means he has difficulty distinguishing between those two colors. Blue, however, is the most vivid color he can see clearly, so it made sense for him to use blue as the primary color for the platform.
Since its launch in 2004, Facebook has used blue as its dominant color, a decision that has since become synonymous with the platform itself. The blue hue is not just functional but has also become a branding signature that millions of users worldwide associate with Facebook. The color helps with visibility and user experience, creating a clean, non-distracting interface for users as they interact with the platform.
The blue color of Facebook also evokes feelings of trust and calmness, making it appealing to users and helping maintain a positive association with the platform. The simple yet effective design choice has contributed to Facebook’s success as one of the most popular social media platforms in the world.
7. 1 Minute of Video = 1.8 Million Words
According to Forrester Research, one minute of video content is equivalent to 1.8 million words. This comparison underscores the power of video as a medium for communication. Videos have the ability to convey information in ways that text and images cannot, making them an essential tool for digital marketing, learning, and entertainment.
Video combines visual and auditory elements, which help to engage the brain more effectively, making it easier for people to absorb and retain information. With the rise of platforms like YouTube, TikTok, and Instagram, video content has become more accessible and popular than ever. This fact highlights why video is so effective in marketing, where a short 30-second video ad can sometimes convey more than an entire webpage of text, making it a powerful tool for brands and content creators.
For marketers, video is an essential tool to create emotional connections with audiences, deliver messages more clearly, and drive engagement. Whether it’s an explainer video, a product demonstration, or a tutorial, videos are a highly effective way to communicate messages.
