The logo is a non-profit organization and eponymous website led by brothers Hadi and Ali Partovi[1] that aims to encourage people, particularly school students in the United States, to learn computer science.[2] The website includes free coding lessons, and the initiative also targets schools in an attempt to encourage them to include more computer science classes in the curriculum.[3] On December 9, 2013, they launched the Hour of Code 2013 challenge nationwide to promote computer science during computer science week until December 15, 2013.[4] Major tech companies and their founders, including Bill Gates and Facebook’s Mark Zuckerberg, have put up about $10 million for[5] [6]


According to its website, has the following goals:[3]

  • Bringing Computer Science classes to every K-12 school in the United States, especially in urban and rural neighborhoods.
  • Demonstrating the successful use of online curriculum in public school classrooms
  • Changing policies in all 50 states to categorize C.S. as part of the math/science "core" curriculum
  • Harnessing the collective power of the tech community to celebrate and grow C.S. education worldwide
  • Increasing the representation of women and students of color in the field of Computer Science.


Launch and first video release[edit] was launched in January 2013 by Hadi and Ali Partovi, with the goal of making "programming" accessible to everyone. Their initial focus was on creating a database of all computer science classrooms in the United States.[7] The launch was covered in a number of technology publications online, including TechCrunch,and Geekosystem.[7][8] In late February 2013, a month after launch, they released a video featuring Mark Zuckerberg, Bill Gates, Jack Dorsey and other programmers and entrepreneurs on the importance of learning to code. This video was covered in a number of news sources.[9][10][11][12] Two weeks after the launch, TechCrunch reported that the video had been a "blockbuster hit".[13]

Hour of Code challenge[edit]

During Computer Science Education Week [14] from December 9 to December 15, 2013, launched the "Hour of Code Challenge" on its website to teach computer science to school students, enticing them to complete short programming tutorials.[15][16] [17] [18] The challenge involved getting people to write short snippets of code to achieve pre-specified goals using Blockly, a visual programming language of a similar flavor as Logo. The initiative had been announced about two months in advance.[19] At the time of launch, the initiative was supported by United States President Barack Obama as well as leaders of many technology companies such as Microsoft and Apple Inc..[20][21] About two weeks later, it was announced that over 20 million people had participated and over 600 million lines of code had been written as part of the challenge.[22][23][24]

Flappy Bird[edit]

In 2014, posted a one hour tutorial to build and customize a Flappy Bird video game using the site's block visual programming language.[25][26]

An Hour of Code for Every Student crowdfunding campaign[edit]

In December 2014, held a successful Indiegogo crowdfunding campaign that raised over $5 million to help educate school children.[27]


Writing for San Jose Mercury News, Mike Cassidy praised and the Hour of Code, writing: "A publicity stunt is what we need."[28]

John Dvorak was critical of the Hour of Code in an article for PC Magazine. Dvorak wrote: "I see it as a ploy to sell more computers in schools."[29]

Earlier, Dave Winer had responded to's first video launch by writing: "I don't like the way people at are pitching it. And I don't like who is doing the pitching, and who isn't. Out of the 83 people they quote, I doubt if many of them have written code recently, and most of them have never done it, and have no idea what they're talking about."[12]
