Diamond Comics 2008 Sales figures show:

•Marvel and DC continue to dominate the industry: Marvel took in 41% of retail sales, DC 29% and Dark Horse 6.5%.

•Marvel Comics' Secret Invasion #1 was the best-selling comic book of 2008. The eight-issue miniseries about the takeover of superheroes by shape-shifting Skrulls took the first six spots. Only Uncanny X-Men #500 (No. 7) and DC Comics' Final Crisis #1 (No. 9) also cracked the top 10. Diamond did not release actual sales figures, but best-selling comic books (priced at $2.99 or $3.99) normally sell more than 100,000 copies.

•Among graphic novels, DC Comics dominated, taking seven of the top 10 positions. DC's reprint of Watchmen, Alan Moore's breakthrough graphic novel from 1986, was the top seller, propelled by anticipation for the film due March 6.
