Hmm. Not sure if this is right, but you could do this using idioms. I slightly altered your original sentence.
"To take into/Taking into consideration (my opinion) that TV is one of the greatest scientific achievements of our times..."
Or "In consideration of the fact that TV is one of the greatest scientific achievements of our times..."
A possible alternative, "The/My consideration that TV is one of the greatest scientific achievements of our times" may not be grammatically wrong, but it sounds weird.
