The Entire D6 Interview With Microsoft's Bill Gates and Steve Ballmer (2 of 6)

We’re posting all the interviews from the sixth D: All Things Digital conference that took place in late May.

But–as many readers have requested–they will all be available in their entirety over the next few weeks in this column.

Here’s Part 2 of 6 of our discussion with Microsoft Co-Founder Bill Gates and CEO Steve Ballmer, who were interviewed together by Walt Mossberg and me on the conference’s opening night.

(I will be posting one video part of the Gates/Ballmer interview every day this week, including Saturday.)

In this video, Gates and Ballmer talk about their roles in building Microsoft (MSFT) into a global tech powerhouse together.
