Old school CRT TVs and monitors most definitely rebroadcast what they are displaying [1]. Modern TVs still do, but not at the same power levels. I would guess that a tempest attack on a modern TV is very difficult. I don't know if the BBC has ever used any of these techniques. But it's not impossible.
