How did photography and sound impact communication history?

The invention of photography and the ability to record sound and apply it to the images, profoundly impacted communications in this era.  As we learn from our Communication in History text, early photographers started working for newspaper outlets, as more technologically advanced cameras came into fruition.  With the increase in newspapers and magazines, and with the ability to photograph individuals and provide newsworthy information to go with the photos, more and more communications evolved as a result.  

Even Presidents McKinley and Roosevelt began to use the new age of technology.  Where past presidents would only be able to have a stage photo taken, with the invention of "Moving pictures"  action shots could be taken and distributed via the newspapers printing that would show these men in action.

These newspapers then evolved into producing sound footage to put sound with the pictures they were taking to include ones voice in conjunction with the pictures, adding another dimension to the communication process.
