Consumer Technology Association president Gary Shapiro said the event, once used to launch the world's first video cassette recorder, would host more than 4000 companies this year, from the big players to more than "800 start-up companies". "Again, thank you for your patience during this time", explained the CES Twitter account, at 4:20 p.m. EST.
CES said in a statement that the outage was caused by "condensation from heavy rainfall" that sparked a flashover on one of the building's transformers.
Some publicists even tried to exploit the power outage. The massive four-day show officially opens Tuesday.
In addition to cutting-edge consumer technologies, this year's CES attendees can also - as usual - expect to see offbeat, concept, and unusual innovations. "The most popular exhibits, however, are from our companies like Samsung Electronics and LG Electronics that display the most advanced technologies".More news: Khan fight no issue for Spence
Fellow South Korean tech giant Samsung was rumoured to be ready to fire back with a 150-inch television using new "Micro LED" technology, however, that could replace its current QLED television range and challenge OLED technology. Parts of South and Central Halls, where numerous exhibitors are set up to showcase their products, have been thrown into darkness.
"After coming to CES for so many years with all of the power draw that this show puts on, I was surprised that happened because it's never happened before to my knowledge", says Tim Alessi, head of home entertainment product marketing for LG Electronics USA.
Thousands of keen analysts, media and buyers were also kept from entering the Convention Centre's North Hall, which connected to the powerless section. Folks still leaving Central Hall and not let in.
