The major global rollout of COVID-19 vaccines, which began at the end of 2020, continued in 2021. Most major events scheduled for 2020 that were postponed due to the pandemic were hosted in 2021, including the 26th United Nations Climate Change Conference, Expo 2020, and sporting events such as UEFA Euro 2020, the 2020 Summer Olympics and Paralympics, as well as the 2021 Copa América.
2021 additionally witnessed numerous advancements in space exploration, particularly by the United Arab Emirates, NASA and SpaceX, including the launch of the James Webb Space Telescope.

Samsung Group (Korean: 삼성; Hanja: 三星; RR: samseong [samsʌŋ]; stylised as SΛMSUNG) is a South Korean multinational manufacturing conglomerate headquartered in the Samsung Town office complex in Seoul. The group consists of numerous affiliated businesses, most of which operate under the Samsung brand, and is the largest chaebol (business conglomerate) in South Korea. As of 2024, Samsung has the world's fifth-highest brand value.
Founded in 1938 by Lee Byung-chul as a trading company, Samsung diversified into various sectors, including food processing, textiles, insurance, securities, and retail, over the next three decades. In the late 1960s, Samsung entered the electronics industry, followed by the construction and shipbuilding sectors in the mid-1970s—areas that would fuel its future growth. After Lee died in 1987, Samsung was divided into five business groups: Samsung Group, Shinsegae Group, CJ Group, Hansol Group, and JoongAng Group.
Key affiliates of Samsung include Samsung Electronics, the world's largest information technology company, consumer electronics maker and chipmaker by 2017 revenues; Samsung Heavy Industries, the world's second-largest shipbuilder by 2010 revenues; and Samsung Engineering and Samsung C&T Corporation, ranked 13th and 36th among global construction companies, respectively. Other significant subsidiaries are Samsung Life Insurance, the 14th-largest life insurance company globally, Samsung Everland, operator of Everland Resort (South Korea's oldest theme park), and Cheil Worldwide, the world's 15th-largest advertising agency by 2012 revenues.

A great upgrade! Especially since this replaced my LN52A750 that I had purchased in 2007 (which still works perfect). I am on day 5 with the Neo Qled and it is absolutely amazing. I am still in the learning curve with getting used to all of the great features and functions that are new to me. But hands down the picture quality is impressive! Even the sound is great. I am glad I did my research into new tv’s and ended up selecting the 65″ Neo Qled. I’ve been a Samsung fan for decades and will continue to be. Thank you for the great products.

I use my TV for work, school, competitive gaming, movies, and streaming. I have it hooked up to my console and my PC and I use it for both all the time.
I personally LOVE game motion plus and the AMD FreeSync that comes with my tv, as well as the super high contrast and black levels that come with the new MINILED technology. I get black levels that turn off parts of my screen for the best visual effect and I get crystal clear 4k imagery that makes it look real, like I’m right there at the place or thing that I’m looking at.
The way this TV handles black level and contrast is fantastic. This TV will handle ANY 4k imagery, and I could honestly find any image online and connect it to my TV and just stare at it as long as I want, it’s amazing, and the colors are SUPER saturated! There’s no lack of color in any image.
