However both shows didn't air only on Disney Channel, Disney XD, Nickelodeon and Nicktoons, in early 2020 both shows's syndicated rights were brought by Discovery, Inc. and Hasbro for their Discovery Family channel, making them 1st syndicated programs on the network. Various promos and bumpers were made for both series, like one had Phineas and Felicity introduce themselves to audience, with other characters like Ferb, Miguel, Candace, Athena, Buford, Yana, etc. showing up later, with Perry showing up last, with Phineas saying "Oh, there you are Perry!" with Felicity saying "What is Perry anyways?". In March 2022 both shows were removed for unknown reasons, some people say it's because Discovery, Inc. and Hasbro lost the rights to air both series.
