Unless you've been living under a rock for the past five years, you know that video games are big. Huge. "Grand Theft Auto IV" made $500 million its first week. Revenues for the whole dang industry are up 30 percent over last year (in the United States, anyway). Your grandma owns a Nintendo Wii.
Call me cautious, but for every yin, there's a yang. What goes up must come down. Scan today's headlines (or yesterday's … or last week's) for evidence of other formerly hot industries that are now in the tank.
So, can the video game trajectory last?
