The 19th and 20th centuries has seen a lot of improvements. It's clear that thing continue to improve in a lot of domains, but it is not clear that it accelerates. IMO 1995-2005 has major impacts compared to 2005-2013.
In my opinion nothing can beat the beginning of 20th century. Cars, airplanes, phones, television, radio - all that originated (or have been widely adapted) one hundred years ago. Internet and smartphones are inventions from the last 20 years, before that I can't think about any inventions that drastically changed our every day life.
Don't forget quantum mechanics, relativity and the discovery of the expanding universe, also all around that time. The last one wasn't really an innovation to be fair.
