What happened to Norton 360?

After being plagued with the IE 11 crashing problem last night, I checked other things and noticed that Norton / Symantec no longer offers Norton 360 products. I have questions. Is Norton 360 still supported? I have licenses that I have not used yet, so how long before support will be discontinued for Norton 360? Can I still renew current Norton 360 accounts by entering the new key / code from a newly purchased Norton 360 retail product, and for how much longer (years)?

Thanx for many years of nearly flawless protection, to you Norton / Symantec reps, and I hope that this continues.
