The CES Las Vegas site features everything from event schedules and exhibitor lists to coverage of emerging tech trends and highlights from CES Innovation Award winners across various categories, including AI, health, and sustainability.
The event is technically a “trade” event, designated only for industry professionals. Roughly 170,000 attendees pass muster to get in, and according to this blog post, not all of them adhere strictly to the standard qualifications. Sometimes folks create a false credential or simply buy unused tickets from absent industry pros, while others sneak in.
Noon had been determined independently at each location based on when the sun was highest in the sky, but this became impractical for standardizing transportation. British star-mapping and navigation advancements established Greenwich as the prime meridian through Greenwich Mean Time, or GMT.
This centennial page explores the Consumer Technology Association’s 100-year history, from its founding in 1924 shortly after the invention of the radio, to its leadership of CES Las Vegas. Read through the history of the wireless age and how it gave birth to a growing consumer electronics movement.
The strip has more than 100,000 hotel rooms and the sprawling Las Vegas Convention Center where some of the convention takes place. Sin City’s alluring attractions combined with these logistics perks make it a common destination for big-time gatherings like CES.
The rapid development of integrated circuits—the basis of computing power—in the 1960s catalyzed an industrial shift toward miniature devices, including pocket transistor radios, smaller TVs, and more. This first consumer electronics trade show (with a slate of 117 exhibitors and 17,000 attendees) sought to make everyday electronics accessible and portable. See a timeline of early consumer tech with photos.
Equal to about 5.39 × 10⁻⁴³ seconds, the unit is derived from calculating how long it would take light to travel the Planck length—the smallest theoretically measurable length. Quantum physics allows events to occur on smaller timescales, making them undetectable and their order to lose meaning.
By combining imaging from ground- and space-based telescopes designed to capture specific wavelengths of light, phenomena across a range of energies can be observed. If limited to a single frequency range, astronomers would not be aware of some cosmological events, such as those whose visible light is blocked by dust.
In "Velocity Raptor," space and time warp as you make your way across a room of obstacles at "normal" speeds. Take advantage of these relativistic effects to solve puzzles involving clocks running at different rates and colors shifting as a result of your movement.
The phenomenon, known as the Doppler effect, is the result of experiencing an increase in the frequency of observed waves when approaching a source and a decrease when moving away. Because this property corresponds to color, approaching objects appear bluer than normal—blueshift—and receding objects appear redder than usual—redshift.
