Television has come a long way—from a bulky box sitting in the corner of the living room to an ultra-slim smart device that connects us to the entire world. The journey of TV technology is one of the most fascinating shifts in home entertainment, blending innovation, internet, and interactive experiences.
In this article, we explore how TVs evolved over the decades and transformed into the intelligent Smart TVs we use today.
1. The Beginning: Cathode Ray Tube (CRT) TVs
The earliest TVs were powered by Cathode Ray Tube (CRT) technology. These TVs were:
- Heavy and box-shaped
- Limited to standard definition
- Available in black-and-white first, then color

Despite limitations, CRT TVs introduced the world to home entertainment and shaped a new era of media consumption.

Key improvements:
- Slim and lightweight
- Better picture quality
- Larger screen sizes became affordable
- Energy-efficient compared to CRT
This era marked the beginning of modern TV design—sleek, stylish, and wall-mountable.

When HDTVs arrived, viewers experienced clarity like never before.
Features of the HD generation:
- 720p and 1080p resolutions
