25 years have passed since the debut of the first version of the google search to quickly retrieve the right information on the web and from 1997 (the year of the domain registration) to today, innovations have added brick after brick to build a much more extensive and profound service than would ever have been imagined a quarter of century ago. We participated in an online panel discussion with Danny Sullivan, Public Liaison for Google Search, which retraced the most important stages of the evolutionary journey of Google Search. It all started the year before, in 1996, with the PageRank algorithm developed by the founders Larry Page and Sergey Brin as part of a research project at Stanford University, to evaluate the quality of a page compared to another in terms of the quality and quantity of links that connect it.
It was 1998 when the first Doodle, dedicated to the Burning Man festival in the Nevada desert with the two founders who changed the logo to inform of the absence of the team in the office, while in 2020 it is time for the first international Doodle signed by the then intern Dennis Hwang on the anniversary of the storming of the Bastille. The same year Google is already available in ten languages, including Italian and the index reaches one billion URLs considered. 2001 saw the debut of the AdWords advertising platform and the “Maybe you were looking …” that correct the spelling for more precise search results and Google Images, inspired by visual and unsolicited results from the extensive research on the bold green low-cut dress worn by Jennifer Lopez at the Grammy Awards. 2002 inaugurates important innovations such as Year-end Zeitgeist which summarizes the most popular searches of the last 12 months, the spread of Google’s bees dedicated to developers who want to exploit the search potential within their work and the Google News platform which collects news from various sources.
In 2003 here is the first easter egg with the online calculator that opens the result 42 looking for “The answer on life, on the universe and on everything” quoting the The Hitchhiker’s Guide to the Galaxywhile in 2004 the automatic completion which is based on the volume of searches and on geolocation, promising to speed up typing times, but undoubtedly also being responsible for conveying users. In 2005 Maps and Weather arrived plus optimized search for smartphones. In 2006, other services that are still widely used today emerge, such as Google Translate and Google Trends, which display search volumes in a deeper way. In 2009 comes the voice search that translates the voice into commands, but also the ads with product details. In 2010 Google introduces the new indexing system called Caffeine which provides 50% more up-to-date results and useful image search to find results starting from a photo to upload or link.
In 2014 the system was updated to Hummingbird (hummingbird) that tries to better understand the searches with a language closer to that of every day and colloquial, especially in the case of direct questions and the Snippets arrive, that is the useful boxes with portions of posts, articles or other contents from the results of Research. In 2016 comes the most precise neural machine translation and ad optimization through machine learning, while in 2017 there is Lens to search naturally by “showing” what you have in front of the system via the camera, with text translation in real time in 2019 and land on desktop in 2021. For the Covid-19 pandemic, Google introduces information since 2020 important with a dedicated portal that tries to convey users to confirmed and reliable sources. Here is the dedicated portal to the evolution of Google search with the timeline to explore.
