Context paragraphs:
Cicada 3301: Cicada 3301 is a name given to an organization that on six occasions has posted a set of puzzles and alternate reality games to possibly recruit codebreakers/linguists from the public.  The first internet puzzle started on January 4, 2012, and ran for approximately one month.  A second round began one year later on January 4, 2013, and a third round following the confirmation of a fresh clue posted on Twitter on January 4, 2014.  The stated intent was to recruit "intelligent individuals" by presenting a series of puzzles which were to be solved.  No new puzzles were published on January 4, 2015.  However, a new clue was posted on Twitter on January 5, 2016.  In April 2017 another PGP signed message was found: "Beware false paths.  Always verify PGP signature from 7A35090F."  That message explicitly denies the validity of any unsigned puzzle, as recently as April 2017.

Google added advertising to its finance page on November 18, 2008, which continues to be shown.  Google launched a revamped version of their finance site on December 12, 2006, featuring a new homepage design which lets users see currency information, sector performance for the United States market and a listing of top market movers along with the relevant and important news of the day.  A top movers section was also added, based on popularity determined by Google Trends.  The upgrade also featured charts containing up to 40 years of data for U.S. stocks, and richer portfolio options.  Another update brought real-time ticker updates for stocks to the site, as both NASDAQ and the New York Stock Exchange partnered with Google in June 2008.  It has not undergone any major upgrades since 2008 and the Google Finance Blog was closed in August 2012.  Enquiries and bug reports are not responded to or acted upon so it is presumed to be a discontinued service.  On September 22, 2017, Google confirmed that the website is under renovation and the portfolios feature won't be available after mid-November 2017.
