TVs have dramatically decreased in price over the past 25 years, primarily due to advancements in liquid crystal display (LCD) technology and manufacturing efficiencies. Key factors include the scaling up of mother glass sheets, improved manufacturing processes, and higher yield rates, which have all contributed to the significant reduction in cost.

• LCD manufacturing shifted to ever-larger "mother glass" sheets, letting factories cut many more panels from each sheet and slashing per-unit cost.
• Manufacturing process improvements and higher yield rates (fewer defective panels per batch) drove costs down further.
• These combined efficiencies explain why TV prices have fallen dramatically over the past 25 years.
