The announcement was made back in 2010 by ABC/Disney.
In a press release, Disney co-chair Anne Sweeney explained the decision, saying:
"The launch of Disney Junior in the U.S. is the next step in our global preschool strategy, which began 10 years ago with the premiere of our first dedicated preschool channel in the UK. The decision to ultimately transition SOAPnet to accomplish this was not arrived at lightly. SOAPnet was created in 2000 to give daytime viewers the ability to watch time-shifted soaps, before multiplatform viewing and DVRs were part of our vocabulary. But today, as technology and our businesses evolve, it makes more sense to align this distribution with a preschool channel that builds on the core strengths of our company."
