The first TV screens were round too, but they decided ultimately on a rectangular format, historically film, as a useable medium in strip format had to force a rectangular format for the frame, (square is a special case of rectangle)
It wasn't until the Kodak disk camera, that a format could be made in any shape, but it wound up using rectangular film, because that still represented the machines that processed the negative strips to begin with.
Today, we could have round sensors, but when all is said and done, it is much more efficient to process a large number of rectangles out of a big circular silicon chip, than a sequence of circles.
