Reddit unveiled changes to its public front page, called r/popular, in 2017; the change creates a front page free of potentially adult-oriented content for unregistered users. In late 2017, Reddit declared it wanted to be a mobile-first site, launching several changes to its apps for iOS and Android. The new features included user-to-user chat, a theater mode for viewing visual content, and mobile tools for the site's moderators. "Mod mode" lets moderators manage content and their subreddits on mobile devices. Reddit launched its redesigned website in 2018, with its first major visual update in a decade. Development for the new site took more than a year. It was the result of an initiative by Huffman upon returning to Reddit, who said the site's outdated look deterred new users. The new site features a hamburger menu to help users navigate the site, different views, and new fonts to better inform redditors if they are clicking on a Reddit post or an external link. The goal was not only for Reddit to improve its appearance, but also to make it easier to accommodate a new generation of Reddit users. Additionally, Reddit's growth had strained the site's back end; Huffman and Reddit Vice President of Engineering Nick Caldwell told The Wall Street Journals COI Journal that Reddit needed to leverage artificial intelligence and other modern digital tools. Registered users can opt-out from the redesign and use "Old Reddit" which continues to use the previous design. Unregistered users can access it via old.reddit.com. Logo Reddit's logo consists of a time-traveling alien named Snoo and the company name stylized as "reddit". The alien has an oval head, pom-pom ears, and an antenna. Its colors are black, white, and orange-red. The mascot was created in 2005 while company co-founder Alexis Ohanian was an undergraduate at the University of Virginia. Ohanian doodled the creature while bored in a marketing class. Originally, Ohanian sought to name the mascot S'new, a play on "What's new?", to tie the mascot into Reddit's premise as the "front page of the Internet". Eventually, the name Snoo was chosen. In 2011, Ohanian outlined the logo's evolution with a graphic that showcased several early versions, including various spellings of the website name, such as "Reditt". Snoo is genderless, so the logo is moldable. Over the years, the Reddit logo has frequently changed for holidays and other special events.
