Made small empire out of $25 machine bought in 1946: Buffett

In a video showing Warren Buffett visiting a candy store with 'best friend' Bill Gates, Buffett says, "I bought a [pinball] machine for $25 in 1946 and built a small empire out of it." Calling it the best business he was ever in, Buffett added, "I peaked very early in my business career. It's been all downhill ever since."
