Which of the following is an example of a product that has evolved over time?

The choice of televisions as a product that has evolved over time is accurate because televisions have undergone significant transformations since their inception. Initially, they were bulky, black-and-white devices with limited functionality. Over the decades, advancements in technology have led to the development of color televisions, flat-screen TVs, and smart TVs, which integrate internet connectivity and streaming services. Each iteration introduced improvements in picture quality, sound, and user interface, showcasing how consumer electronics can adapt to changing technology and consumer demands.

The evolution of televisions reflects broader trends in innovation, including advances in display technology, such as LED, OLED, and QLED screens, as well as changes in the way content is consumed, shifting from traditional broadcasting to on-demand streaming. In contrast, while options like paper clips, smartphones, and pencil sharpeners have also seen changes, the extent and impact of innovation in televisions highlight a more profound evolution in the product's design and functionality over time.
