WebRTC and Its Impact on the Unified Communications Landscape

Johannes Gutenberg invented the printing press with movable type in 1455. Nearly 195 years later people held the first daily newspaper in Leipzig, Germany. Fast-forward another 226 years when Alexander Graham Bell patented the electric telephone. It’s amazing to think how much technology has advanced and how many different options we now have to communicate, from instant messaging to video.

As the amount of time between advancements continues to narrow, particularly with communications, businesses are also able to shorten their adoption cycles of … Continued
