Microsoft chairman
Bill Gates went wrong, as his demonstration of the
Xbox 360 resulted in an
out of memory error, much to the amusement of the onlookers.
Samsung showed off a
plasma television. Zimiti Ltd (renamed Boardbug Ltd in 2007) won the "Best of Innovators" award for Personal Electronics. It is the only British company to have won this award.

Intel Core i7 processor. One computer ran two screens, displaying 576 cubes hooked up to 20,000 information sources, including 20 live video feeds. Visitors would touch one of the cubes, and an infobox displaying that content would come forward. One journalist explained, "The graphics on the giant screens were a tons of fun to move around with their uncanny quickness and smooth motion, and the whole thing felt super responsive, Giving us a peek into the future, it seemed a lot like that computer screen in the movie
Minority Report. It was the most spectacular demo we saw at CES 2010." Equally impressive, Parrot presented the first prototype of Parrot
AR.Drone, a remote-controlled flying toy which streams video via WiFi to an iPhone. Sustainable Planet grew by 40% in 2010.

Ivy Bridge processors. AMD demonstrated their new

Photo Marketing Association held its annual trade show in conjunction with CES, with the PMA show branded as PMA@CES.
2013 The 2013 International CES, instead of starting on Thursday went from Tuesday to Friday, January 8–11, 2013, in the Las Vegas Convention Center, Las Vegas, Nevada, United States. Over 3,000 exhibitors showcased a wide range of innovative products this year. CES 2013 was known for what was billed as an insane opening by
Qualcomm. This year the categories include 3D, Accessories, Audio, Automotive Electronics, Embedded Technology, Lifestyle Electronics, Wireless & Wireless Devices to name a few. 2013 International CES however was not necessarily being noted for announcing the newest products, but getting a lot of press for the fundamental changes about to hit the digital world; such as motion detection sensors, the driverless cars and digital home safety and technology. Major announcements during this edition were: • Samsung unveiled multi-view TVs and Flexible OLED Display Youm • Sony announced
Sony Xperia Z smartphone, and Samsung Announced
Galaxy S2 plus smartphone. • Sony announced TRILUMINOS quantum dot display technology. • Qualcomm unveils Snapdragon 600 & 800 processors that can bring 4K recording capability in Mobile Phones • Intel revealed ATOM processor for embedded markets as well as Bay Trail • Panasonic announced a wide range of smart TVs.

2014 The 2014 International CES was held during the week from January 7 to 10, 2014, in the Las Vegas Convention Center, Las Vegas, Nevada, United States. The first
Li-Fi smartphone prototype was presented at the show. The smartphone uses SunPartner's Wysips CONNECT, a technique that converts light waves into usable energy, making the phone capable of receiving and decoding signals without drawing on its battery. The phone also has a transparent
photovoltaic screen that lets light recharge the phone. LG debuted its
webOS on smartTVs and new 77-inch curved OLED Ultra HD TV. Samsung unveiled its curved TVs with two series of concave TVs. ProtectCELL showcased its comprehensive mobile protection plans for all major devices, including the iPhone 5S and 5C, iPad Air, iPad Mini 2 and Galaxy S4. With demonstrations such as blending a Blackberry, ProtectCELL proves they will cover all damages. The AMD presentation mentioned (among others) – the Kaveri CPU of the Steamroller architecture,
Heterogenous System Architecture (HSA) lineup and the intention to build upon that, immersive experience,
Mantle and
AMD TrueAudio. In the Intel keynote presentation, its CEO talked about three areas in which technology can improve: living, working, and playing. He also presented
Intel Edison, a SoC of the SD card format. Pebble announced the
Pebble Steel smartwatch, which has a thin body, tactile metal buttons, and Corning Gorilla Glass.
Laser diodes were unveiled at the show that are going to be used for
high-beam headlights in
Audi vehicles. The high beams will be lasers, though the low beams will be
light-emitting diodes. The car maker says that their high beams have a 500-meter range, which is roughly twice the distance of LED high beams. Lasers are expensive though. Lasers are smaller, brighter and more energy efficient than LED headlamps. Their laser headlamps use less than half the energy of LEDs. Laser diodes can emit 170
lumens per watt, while LEDs generate only 100 lumens. Lasers are sensitive to heat but that has not stopped their production for vehicles. Laser technology is not as advanced compared with LEDs, which have been around for decades.
2015 The 2015 International CES was held during the week January 6–9, 2015, in the Las Vegas Convention Center, Las Vegas, Nevada, United States. The 2015 CES was reportedly the largest in its history, with 3,600 exhibitors and 170,000 professional/industry attendees.

2017 CES 2017 was held January 5–8, 2017, in Las Vegas. Even with tight security at the show, two prototype
Razer triple-screen gaming laptops were stolen during the show.
Min-Liang Tan, co-founder and chief executive officer of

Notoriously, CES received a large amount of negative press and backlash from feminists worldwide for its decision (later reversed) to revoke a CES Innovations Award for a female pleasure device presented to Lora DiCarlo, with CES stating the reasoning for the revocation was "products that are immoral, obscene, indecent, profane, or not in keeping with CTA's image will be disqualified.". The award was later reinstated.
2020s 2020 The 53rd CES was held in Las Vegas, Nevada from January 7 to 10, 2020.

2022 The show ran from January 5 to 7. Although the show was originally scheduled to run until January 8, the Consumer Technology Association decided to close the show one day early, citing public health concerns after many companies pulled out of the in-person event. Due to the increased
SARS-CoV-2 Omicron variant infection counts reported, many companies such as
Intel,
Lenovo,
TikTok,
T-Mobile,
Amazon,
Google, and
