News Stream usually brings you stories about the power of technology to improve our lives. But in 2013, the top tech story was more ominous.
Since June, revelations about the U.S. National Security Agency's surveillance programs have come to light. The fallout has been felt in Washington and the rest of the world.
Tech companies have expressed outrage over the U.S. government's spying practices. Listen to Google's chairman Eric Schmidt in Part 1 (above).
In Part 2, hear from Wikipedia's Jimmy Wales and examine the new generation of gaming consoles.
Finally in Part 3, astronaut Chris Hadfield speaks about his popular videos from space. And we ask what the future holds for mobile technology.
