Based on the provided search results, here are the key reasons why televisions are typically rectangular:

1. **Economics and manufacturing**: Rectangular screens are cheaper and easier to mass-produce than round ones. This is because the manufacturing process involves cutting and shaping glass or plastic to fit a rectangular frame, which is simpler and more cost-effective than creating a curved or round shape.
2. **Aspect ratio and content**: Most TV content, including movies and TV shows, is shot and edited with a rectangular aspect ratio in mind. This means that the majority of programming is designed to fill a rectangular screen, making a round screen unnecessary.
3. **Geometry and viewing**: Rectangular screens are more efficient for displaying rectangular shapes, such as text and graphics, which are common in TV programming. Additionally, the human eye is more accustomed to viewing rectangular shapes, making them a more pleasing and intuitive format for TV viewing.
4. **Historical development**: Early CRT (Cathode Ray Tube) TVs were initially round due to manufacturing limitations, but as technology improved, designers shifted to rectangular shapes to maximize screen area and reduce waste.
5. **Practicality and design**: Rectangular screens provide a more stable and durable design, with fewer corners and edges to compromise the display's structural integrity. This is particularly important for large screens and heavy CRT TVs.

While there have been experiments with round and curved screens, such as the Sony Trinitron WEGA KV-32FS12 (2002) and the Samsung "The Frame" (2017), these designs have not gained widespread adoption due to the factors mentioned above.

In summary, the combination of economic, practical, and design considerations has led to the widespread adoption of rectangular TV screens, making them the standard for the industry.
