Root Causes
Pocket, originally launched as Read It Later in 2007 by Nate Weiner, defined the read-it-later category alongside Instapaper. Mozilla acquired Pocket in 2017 for an undisclosed sum, folding it into Firefox as a New Tab recommendation surface. On May 22 2025 Mozilla announced it would shut down both Pocket and Fakespot (another acquired product) on July 8, 2025, citing a refocus on 'what powers better browsing.' The read-it-later category itself has been decimated: attention shifted to TikTok/YouTube, AI summaries replaced 'save for later,' and native browser reading modes made third-party apps redundant. Pocket exports were made available for 90 days.
