3D TV
Back in the day when you had to wear those red and blue glasses, 3D movies were a major novelty. Because it didn't actually operate effectively and detracted from the rest of the film, it was never more than a novelty.
Modern 3D is a vast improvement. A more seamless experience without the use of colored lenses. Although not everyone prefers it and paying that way to watch movies is expensive, it became commonplace in major Hollywood blockbusters after the phenomenal success of Avatar. In fact, it was so significant that the 3D TV attempted to cash in on it. When 3D is available at home, why wait to see a movie?
The cost of a brand-new 3D TV is about $2,000. For 3D movies, you also need a Blu-Ray player. You then required 3D glasses. Everyone needed a pair to watch, and they were about $100 each. Additionally, because the TV didn't function properly at angles, they had to sit exactly in front of it.
The majority of movies aren't made in 3D, and some are only made in 3D after the fact for certain moments. Users were thus spending a lot of money for a restricted experience. Overall, the technology wasn't appreciated or valued by enough individuals to justify the associated expenditures.
