People in the US spent a record $10.8 billion (about 79 billion yuan) online during this year’s Black Friday. Adobe Analytics, a data collection and analysis platform, reported on Nov 30 that total (总的) sales were 10.2 percent higher than they were in 2023. Each year, Black Friday marks the start of the year-end holiday sales season in the US. This year’s biggest sales were in toys, skin care products (护肤品) and clothes. Artificial intelligence (AI, 人工智能) played a big part in this year’s Black Friday success. With AI’s help, people can quickly find what they want and get the best deals.
