When browsing through the updates on the timeline, I noticed that Ultra HDTV or 8K or 4320p TV with 16 times the resolution of HD being common in households in 2020 is rather inaccurate.
4K TVs which are 2160p are just now being introduced and are extremely expensive. Hell, even HDTVs are only now getting adopted by low income families.
By 2020, 4K TVs will start to get adopted in more and more families, not 8K. That would probably take another several years.
