Consumers who were stuck at home turned to video entertainment, and Roku (NASDAQ: ROKU) was a huge beneficiary, as its stock soared 148% in 2020. There's no denying that Roku's operations faced a serious slowdown in 2022, with revenue rising 13% year over year, a big decline from 55% growth in 2021. Management cited the weaker macro environment, which not only reduced Roku's hardware sales, but also hurt the ad market.
