Amazon, Facebook, Twitter and Pinterest announced on Tuesday that they would not send teams to the Consumer Electronics Show (CES) in Las Vegas as worries about the Omicron variant is increasing. T-Mobile also said that the majority of its contingent would not be present, and its CEO will not be delivering a speech in person or virtually at CES.

CES in the past has attracted over 180,000 people from around the world to casinos and convention spaces in Las Vegas and served as an annual showcase of new trends and gadgets in the technology industry. The Consumer Technology Association, which runs CES, had said that the show will start on Jan. 5 and will end by Jan. 8. Health precautions will include full-vaccination requirements, masking and the availability of Covid-19 tests, the association said in a statement.
