Noticed in the credits it's now "DPS/Film Roman." When did it change? (DPS apparently stands for Digital Production Solutions, according to the website, but the company is still referred to all over the site just as Film Roman.)
Interesting to note that it's owned by telecom company IDT.

Al Jean said that starting with the 14th season (the EABF__ episodes) the should would be moving to digital coloring, putting them in line with the way most other cartoons are produced. Perhaps DPS is doing the coloring work.
