3D Television

3D Television remains the most expensive living-room fad in consumer electronics history, with every major brand—Samsung, Sony, LG—pushing active-shutter glasses that cost over $50 per pair. Sales peaked at 3 million units in 2013, then plummeted 60% within two years as viewers refused to wear clunky eyewear at home. These sets demanded 120Hz panels and dedicated HDMI 1.4 ports, adding $200–$400 to a TV's price compared to standard 2D models, and content access required a $300 Blu-ray player. Unlike Amazon Fire Phone (#9), which failed quickly, 3D TV lingered for years because manufacturers kept bundling it into higher-end lines, delaying market rejection but driving up average TV prices by 15%.
