1985 (ITV Winter)
Featured jolly game segment "Knock Your Block Off" (affectionately known as KYBO), which ran rather longer than TX itself.
Co-production between Granada and Central (Central did KYBO and Granada did everything else).
TX is telly-speak for "transmission".
Title sequence was a giddy whirlwind of early computer graphics, somewhat reminiscent of the BBC's Six o'clock News.
