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".
The CES global trade show that seeks to extol the wonders of our connected world just illustrated a big Achilles' heel: Without electricity, not much happens.
The Central Hall houses the giant booths for the show mainstays, including Sony, Samsung, LG and Intel, according to CNET.
The Consumer Electronics Show was shut down briefly due to a blackout.
CES Tech West: Located at the Sands Expo and Venetian Hotel, The Palazzo, Wynn Las Vegas and Encore at Wynn. Power in the South Hall was restored within minutes, and power has now been fully restored to all areas. "Again, thank you for your patience during this time", explained the CES Twitter account, at 4:20 p.m. EST. "Even without power, #CES2018 still can't match the ideal black of an #LGOLEDTV".
Officials blamed condensation from heavy rainfall, causing "a flashover on one of the facility's transformers".
Some publicists even tried to exploit the power outage.
While the description of his keynote focuses on the power of technology and Intel's latest advances, Krzanich is also expected to address two key concerns that arose last week - the "Meltdown" vulnerability and his personal sale of stock shortly before news of the vulnerability went public.
In addition to cutting-edge consumer technologies, this year's CES attendees can also - as usual - expect to see offbeat, concept, and odd innovations.
Not all technology at the show immediately came back to life, however.
TV maker LG's OLED Canyon display demo, with 246 OLED panels and more than 30 high-definition generators, took almost an hour to get back in full operation.
Someone is having a bad day!
"Today at approximately 11:15 AM, the Central Hall and South Hall bridge meeting rooms at the Las Vegas Convention Center lost power".
