I'm not sure how deep their expertise really is. I think many of us could have given a more in depth discussion about why home 3D didn't catch on.
Yes it was way overhyped and very expensive at first but what so many overlook is the timeframe in which it came out on the market. According to Leichtman Research Group only 23 percent of US households had a HD monitor by 2008. Other sources cite the figure rising to over 50 percent during the next two years (saw one report which had it at 71% ). Five years later in 2013 Leichtman reported that increased to 75 percent.
And so sales of tv sets in general began to drop, dramatically after 2011 with most consumers having already made their purchases. 3D was just a victim of the time. Some in the industry cited televisions were like a commodity, being upgraded like a computer every two or three years. They were wrong.

So it was introduced to quickly to the consumer public who had just invested in high-definition sets and we're not going to sacrifice those and invest in another monitor. 3D was introduced too soon. And even with that they could have still kept it on as a feature and simply waited for consumers to buy sets again.
