FeedBurner is a web feed tool that was launched in 2004. The best know web feed format is RSS (Really Simple Syndication).
FeedBurner was acquired by Google in June of 2007.
Several years later, Google’s inattention to FeedBurner made it clear that FeedBurner did not have any direct or even indirect monetization potential.
Because of Google’s lack of attention to the app, bloggers began to predict its demise.
