In 1995 some countries started to broadcast a new British teletext protocol called level 2.5. Likely inspired by the French Antiope standard, it had more colours (4016 instead of 7) and redefinable characters. Few people ever saw it, because if your TV didn’t support it you would just see the classic level 1.
