When did Dora get discontinued?

I'm curious to know, when exactly did Dora, the popular children's character and franchise, cease to be produced or marketed? There has been a lot of buzz surrounding the discontinuation of certain beloved childhood icons, and I'm particularly interested in learning about the timeline for Dora's departure from the public eye. Was it a gradual fade-out, or was there a specific date or event that marked the end of her reign as a children's entertainment staple?
