ELI5: Why is Activision acquiring King for ~6 billion dollars? What is the benefit for the company?
gpt
King is a foreign firm so Activision can use money that was mostly sitting in low return bonds (and didn't have many other legal uses without paying a large tax bill).  

King makes money, so Activision will gain King's earnings (about $500 million last year).  

Activision gets experienced mobile developers and marketers which they can combine with their own very well known gaming assets to hopefully create the next big thing in mobile gaming.  

Activision gets access to a massive userbase who are different from their typical customer.
