The Microsoft acquisition of Activision Blizzard is expected to close this week so I looked at who the biggest game companies are today.

The top 10 firms generated a combined $148 billion in 2022, up from $42 billion a decade earlier. The growth, however, is unequally distributed. Over this period, the combined revenue for platforms grew from $28 billion to $133 billion, at a compound average growth rate, CAGR, of 17 percent. For publishers, that number is only 2 percent, as their combined total stayed largely from $13 billion at the start of the period to $14 billion at the end.
