From Publishers Weekly:
Combined graphic novel and comics sales in North America grew 5% to $1.085 billion in 2016, a $55 million increase over the $1.03 billion reported last year.
. . . .
Led by the continuing sales growth of book-format graphic novels (which rose to $590 million, from $350 million in 2015), the $1.085 billion figure represents the combined sales of book-format graphic novels, traditional comics periodicals ($405 million), and digital download-to-own comics ($90 million).
. . . .
Milton Griepp, CEO of pop culture new site ICv2.com, cited the ongoing growth of graphic novels as key to the increase: “This represents growth in the broadest part of the market, where increased variety of content is being found by new audiences for comics, including kids and women.”
