I'm sure no one gave a **** about the 1934 World Cup, either, but 80 years later its the worlds premier sporting competition. People forget that the vision of the tournament isn't on a 4 year time scale, it's more like 15-20 years. You can't force interest in people you have to let it grow organically. The comparative popularity of soccer in the US from 40 years ago vs. now is an apt comparison.
Hell, the NCAA Tournament wasn't near the juggernaut it is now 40 years ago.
