Teen Vogue magazine, which will publish nine editions this year, is shifting next year to a quarterly format, publisher Condé Nast announced Monday morning.

"The new frequency is designed to capture key audience moments relevant to young readers' lives," the company said in a press release. The first quarterly issue, slated to hit shelves next spring, will focus on "young love."

On the business side, Amy Oelkers has been promoted from Teen Vogue's executive head of digital sales to head of revenue. She assumes duties that had been handled since 2015 by Susan Plagemann, Vogue's chief revenue officer and publisher, who continues with oversight of the Vogue mothership.

Condé Nast said it will invest in the digital side of the magazine, and cited online audience growth including a jump to 5.4 million unique visitors in September 2016 from 2.2 million unique visitors in September 2015.

There will be no layoffs stemming from the change in frequency, a Teen Vogue spokeswoman said.

The new quarterly print edition of Teen Vogue, which is intended to be a collectible for readers, will be larger than the magazine's longstanding digest size and more vertical -- the width of today's Teen Vogue but the height of Vogue.

Teen Vogue has paid and verified circulation of 1,007,108, including a subscriber base of 985,382, according to its first-half report with the Alliance for Audited Media.

Last fall, Teen Vogue's business side was merged with Vogue's, though the company shot down a rumor that the magazine would be folded into its larger sibling.

Condé Nast introduced Teen Vogue in 2003 as magazines for teenage girls were particularly hot. It has outlasted many of its rivals, including the now-shuttered Elle Girl, Teen People and CosmoGirl, as digital media increasingly compete for readers and advertisers.
