Google offers so many products that it's often difficult to keep straight what they are and what they do. Some of them have gone away-remember Google+? Google Reader? Google TV? Google Wave?  Memories of these and others are collected at the website Google Graveyard.

Back in September of 2018, the company announced Google Discover, a new feature on the Google app. In a blog post at the time of launch Karen Corby, the group product manager for Google's search products, characterized Discover as "a part of three fundamental shifts in how we think about Search." The shifts, Google said at the time, were "from answers to journeys," "from queries to providing a query-less way to get to information" and "from text to a more visual way of finding information."

Google Discover was a new name and design for an updated version of what was formerly called the Google feed.

Discover uses AI in order to tailor content to articles and information that the algorithm believes will be of interest to the user, based on their past searches and other information. Discover features a card-based interface that organizes information in a way that was new at the time of its introduction.

Users also have the option to use the control icon on the app in order to tell Google whether they want more or less content on that topic. And Discover also shows users evergreen content, although Discover dropped topic bubbles in a feed redesign last summer, and also moved the overflow menu.

Ever since Google Discover launched, SEO experts have published numerous articles trying to master how to get their content featured on there. Google's Gary Illyes, however, warned in late 2019 that publishers should not build their business models around the traffic that comes from Google Discover.

Google last month added features about how to get coronavirus features to Discover, and also to Google Assistant.

According to a report last month from 9to5Google, Google has added a "Report Content" button to Discover, allowing users to report content for four reasons: "Misleading or sensational, Violent or repulsive, Hateful or abusive, and other." The button is located at the bottom right corner of each article on the app.
