Sweet deal

I just got the following NYT “breaking news” email:

Candy Maker Reported Near Deal for Chewing Gum Giant

Mars, the makers of M&M’s, was near a deal last night to
acquire the Wm. Wrigley Jr. Company, the chewing gum concern,
for more than $22 billion, people involved in the talks said.
The transaction would create a confectionery behemoth and
could pressure rivals into a cascade of other mergers

Try as I might to grasp the true economic import of this, I just can’t get past the phrase “confectionery behemoth.”
