I can't see you, but you can see me. Stare at me too long and you'll get lazy. I have to be paid for so I'm not for free. What am I?

The device in question projects images for viewers but does not possess the ability to observe its audience in return. Spending extended periods captivated by its glowing screen often leads to a relaxed, and sometimes overly sedentary, state, thus fulfilling the clue about getting lazy. Furthermore, acquiring this ubiquitous household item requires a financial investment, and often the content it delivers also comes with a price tag, whether through subscriptions for cable or streaming services.

This invention, which began to take shape through various experiments in the late 19th and early 20th centuries, profoundly changed how people received information and entertainment. Scottish inventor John Logie Baird demonstrated the world's first working television system in London in 1926, using mechanical scanning devices. Around the same time, American inventor Philo Farnsworth developed the first fully electronic television system, demonstrating it in 1927. Early televisions were often bulky and displayed images in black and white, a stark contrast to today's vibrant displays.

Over the decades, television technology has continuously evolved from cathode ray tube (CRT) screens to the sleek flat-panel liquid-crystal display (LCD) and LED televisions common today. Beyond its role in leisure, this medium has significantly shaped culture, disseminated news during pivotal historical moments, and provided a window to global events, influencing public opinion and social norms. From a novelty item for a select few, it quickly became a central piece of many homes, offering both educational content and diverse entertainment.
