Answer:The first Black Friday ads of 2021 arrived last month! I saw Costco and Lenovo release theirs on October 25. Compare that to 2020, when the first Black Friday ad drop we saw occurred on October 15. Historically, the first Black Friday ad drop has been kind of random — we've seen dates as early as October 2 or October 5 before, but also as late as October 12 and October 18.
