When did JRPGs start going into decline in the West?

[Darc Requiem]

JRPGs have always been a niche market in the West. Part of the reason is a lack of advertising. FFVII proved that with a strong ad campaign JRPGs can sell. The JRPG with the strongest ad campaign in the West this generation was Lost Odyssey. Considering the fact that Lost Odyssey has sold the most of any JRPG in the West thus far, you'd think that Publishers would see the connection and put forth more of an effort.
