Kelsey Miller's 'I'll Be There for You' will explore both the history of the show and why it continues to find a new audience among younger viewers.

I'll Be There for You, a look at the history and enduring appeal of Friends has been acquired by Harlequin imprint Hanover Square Press for publication in 2019, the 25th anniversary of the show's debut.

The book is pitched in the vein of Seinfeldia, which not only looked at the history of Seinfeld but assessed its cultural impact and was a bit of a surprise hit last summer.

Friends, which debuted on NBC in 1994 and ran for 10 seasons, was one of the biggest hits of the '90s, ranking in the top five most viewed shows for nine of 10 seasons (only missing out in the first season, when it ranked No. 8). It continues to draw about 16 million viewers a week in reruns (and that doesn't include the streaming audience on Netflix). The show is particularly popular among millennials, sparking a whole round of articles exploring why.

The book promises a look at the origins of the show, the numerous high-profile guest stars (Julia Roberts, Brad Pitt, Tom Selleck, Reese Witherspoon and many more) and, of course, Jennifer Aniston's infamous "Rachel" haircut. Plus, it will explore the show's afterlife and why it continues to appeal to people too young to have watched it the first time around.

The book is being penned by Kelsey Miller, a frequent Refinery29 contributor and the author of Big Girl (Grand Central, 2016). John Glynn acquired the book for Hanover Square. Miller was represented by Allison Hunter at Janklow & Nesbit.
