Does Amazon still own Alexa?

Excuse me, I was just reading an article about Amazon's latest acquisitions and I came across a mention of Alexa. I'm a bit confused, as I thought Alexa was a product of Amazon's for quite some time now. So, I'm wondering, does Amazon still own Alexa? I'm curious to know if there have been any recent changes in ownership or if there's been any news about Amazon potentially selling off Alexa to another company. I'd appreciate any clarification you can provide on this matter.
