Typically shows on the same network will decide whether or not two series interact. The best example is Lilo & Stitch: The Series. They had cross-overs with Kim Possible, The Proud Family, and American Dragon: Jake Long. So all of those shows are in the same universe technically, even though they are not mentioned within the other series. You don't see Kim Possible with Jake Long.
