Since last December, Adobe has officially announced the death of Flash, after the severe attack from Apple and Facebook.
As a matter of face, Adobe Flash Professional CC will be replaced by Animate CC from this year onward.
According to Endcoding.com, Flash usage dropped significantly to only 6% in 2015 compared to 21% in 2014.
It is foreseeable that Flash should be completely out within a year or two.
