Activision Blizzard (ATVI)

Why is activision's ticker symbol ATVi? Couldn't it be better to be ACTB, or ABLZ?
What a bizarre chart to see. The premarket, most likely, or after hours trading causes loss in volume yet the price increases. I don't know much about these types of accidents. Is this what happens when a multi million dollar short loses? #tradecryptocurrency and never miss the blip.
