(I know, that's a juvenile play on the tagline from that old Andre Agassi commercial, and isn't meant as any indicator about the company itself since I like the folks there and I like what they do, but I had to have a little fun with this. Besides, who knows how long it'll last?)
Anyway, from iCV2.com:
IDW Makes a Move
Hits #4 Market Share in Comic Stores
Powered by its Whedon (Angel, Spike), Transformers, Dr. Who, Star Trek, and other licensed titles (see “Top 300 Comics—August 2008”), IDW hit the #4 market share rank in comic stores in August, a new high for the company. IDW topped Image, which has generally held the #4 slot. Marvel, DC, and Dark Horse held their customary top three slots.
While one month does not a trend make, IDW has been steadily expanding both its roster of licenses and its in-house titles. At the very least, IDW appears to be ready to compete for a higher rank on an ongoing basis.
