Telephone added to it the computer/smart phone & all the social media attached to it & the camera.....it has created a communication as was never possible before....TV brought a new level of powerful communication at the time of Kennedy & his assassination & with technology being made smaller & smaller & more & more portable & powerful for the individual person's ability to own......life is nothing like it was back in the 60's. The growth has been exponential on comparison as to how slow things were invented in earlier times.

Every invention was important as the stepping stone for the next phase & development.
