Analysis of information sources in references of the Wikipedia article "Yamauchi Hiroshi" in Vietnamese language version.
Yamauchi was listed by Forbes magazine as Japan's richest man just five years ago, when Nintendo was flying high with the launch of the Wii with its motion-sensing controller, although the company's fortunes have since faded as smartphones displace consoles among gamers. His net worth at that time was estimated at $7.8 billion.
