We usually speak of "revolutionary" technology in a purely technological sense - a new hardware or software device that radically changes how we work or entertain ourselves. We call unexpected innovations that improve a product or service and disturb markets "disruptive technology".
Technological advances have changed history, mostly in a positive direction, at least since the invention of moveable type printing in 1439 by Johannes Gutenberg, a German goldsmith. That invention, some 600 years ago, led to an unprecedented era of political change that has greatly increased standards of living, freedom, and liberty we residents of the Earth enjoy. Each of us owes his or her freedom to Gutenberg and others who have invented and used revolutionary technology to enhance the power of the people.
Martin Luther used the printing press to further the Protestant Reformation. People with revolutionary ideas have managed to get the word out despite attempts by the Pope and others to license the printing press.
Censorship in the Soviet bloc was evaded by "Samizdat", a Russian pun for "self, by oneself publishing", where free thinking individuals used typewriten carbon copies, xerox copies, and audio tapes to pass along forbidden materials. Fax technology allowed written materials to be transmitted by ordinary telephones and that has been used to organize revolutionary activities.
Personal computers and printers made it easier for individuals to create revolutionary writings and distribute them via floppy discs or telephone modems.
Of course, the invention of the internet and the World Wide Web has eclipsed all the previous revolutionary technology! Despite attempts by oppressive governments to stiffle dissent and filter internet content, ingenious individuals have found ways to get around these limitations of freedom.
Today, in Iran, the free-thinking dissidents are using the latest communications media, blogs, Flickr, Twitter and cell phone photos and videos to bypass official limitations on communications. Good luck to them!

PS: See Guardians at the Gates are Gone - Freedom of the Press !!! and the links in the right-hand column under the "Freedom" image. Today in the US and most of the rich world, anyone can publish a blog or a "print on demand" book that anyone in the world can access - with no need for official approval or even an agent.
