Each image is the logo of a company or product, whose name can be placed into the blanks alongside it. Going down each column, reading only the boxed letters, gives the final answer, DISTANCE LEARNING.
The third logo on the left, ZEARN, may not be as well known as the others, but it is familiar to the kids who have been learning from home these past few months. Originally, the entire puzzle was going to be logos related to distance learning, but those quickly became far too obscure. Zearn and Chrome are the only two which remain from that original puzzle concept.
