I always thought the reason was because they developed them in the early-mid 50's when round CRTs were still being put in new sets, and metal cone tubes (which had some advantages for shadow mask based tube development) were mostly available in the round screen variants, and due to high set price, already investing too much in color development, and poor color TV sales they did not feel like sinking more money just to make a squarer tube.
