Flush from their apparent success with The New Yorker, publisher Conde Nast followed up as promised on Monday with four new magazine titles for the iPad, all of which use Apple’s new in-app subscription billing.

MacRumors is reporting that in-app subscriptions are now available for four more Conde Nast magazine apps: Vanity Fair, Glamour, Golf Digest and Allure. While the publisher is mum on numbers for their first release, The New Yorker, they’re marching ahead with further titles after promising there would be more to come.

“Today’s rollout follows last Monday's successful debut of iPad subscriptions for The New Yorker, which was the top-grossing app for most of the week,” Conde Nast president Bob Sauerberg announced in an internal memo. “We’re clearly tapping into the enormous appetite consumers have for our award-winning content. Thank you to everyone who worked so hard to bring this next important step in our digital growth to market on schedule. We should all be exceedingly proud of each and every milestone.”

That certainly sounds like success to us, and following up so quickly with an additional four titles would seem to indicate the same. Each of the new titles are monthly publications which will run $1.99 per issue or $19.99 per year, with current print subscribers getting the iPad version for free.

MacRumors also notes that, in keeping with Apple’s new pricing guidelines, the same magazines are also available directly through their respective websites for the same $19.99 per year price. Conde Nast is expected to roll out three more subscription titles by month’s end, with Wired, Self and GQ joining the current five.
