Here's what it's like inside the Berkshire Hathaway shareholder shopping extravaganza

The Berkshire Hathaway annual meeting is an all-out festival.

Berkshire shareholders come in form around the world to see their CEO Warren Buffett speak for hours on Saturday morning.

While Buffett is speaking, there is a shopping event in the convention center adjoining the arena the meeting is held in, but for this year's 50th edition, Berkshire held a second shopping day for the first time.

We went inside to see what the madness was all about.

And for the first few hours, it was, in fact, madness.
