Fox recently discontinued Simpsons box sets. Instead of releasing Seasons 18 - onwards they are instead planning to distribute the episodes on digital platforms. They have released the episodes on FXNow which is only available in the US, which means the rest of us don't get them.

I own Seasons 1 - 17 on DVD and it is very inconvenient for myself and other collectors that we can't complete our collection. I hope we can get enough signatures so that Fox will release the remaining seasons on DVD so all Simpsons fans can enjoy them.
