User blog comment:Mobo85/"Phineas and Ferb" to end in June, but all is not over.../@comment-1518158-20150507233710/@comment-31352869-20150509181125

In terms of how slowly new episodes were aired, I was and am still irritated by how they spread the episdoes out and made season 4 take longer than it should have taken. Another annoying thing that Disney did with P&F was in the lasat year+ air reruns on Disney Channel at night when no one would be able to watch them. These two things really indicated to me that the show was not going to get a fifth season, and made it obvious things were winding down.
