"In old time people had very big TVs. Those TVs bodies were very big but the screens weren't. They had a very big rear part and they were very big if you looked them from the sides as well. They took a lot of space in the room to settle down."
Try perhaps, "in the old days."
In the old days, TVs were enormously wide and deep but they had tiny screens.
