Jack Dorsey## Dorsey's youth and education

Jack Patrick Dorsey was born into a Catholic family on November 19, 1976, in St. Louis, Missouri, USA. His father, Tim, worked for a mass spectrometer manufacturing company, and his mother, Marcia, was a homemaker managing a coffee shop, where Dorsey occasionally worked as a barista.

Dorsey attended Bishop DuBourg High School in St. Louis and worked as a part-time fashion model. After graduating from high school, he studied at the University of Missouri-Rolla (now the Missouri University of Science and Technology) in 1995.

During this time, he hacked into the network of Dispatch Management Company and informed the company's chairman, Greg Kidd, about a software issue. After the incident, Kidd invited him to work.

Dorsey left college, moved to New York and studied at New York University (NYU) under pressure from his parents. At just 14, he programmed software for transportation used by taxi companies. While still a student at NYU, he developed an idea that would later become Twitter. His entrepreneurial zeal led him to drop out of NYU one semester before graduation, despite pursuing an academic path.

Having had a language impairment when he was young, Dorsey was confined at home, where he played computer games and listened to police scanner. Twitter was partly inspired by the short communications that law enforcement officers used. As he grew up, Dorsey was introverted, but over time, he overcame his shyness by speaking in front of crowds.

The Birth and Development of Twitter

In 2006, Dorsey co-founded Twitter with Noah Glass, Biz Stone, and Evan Williams. In 2005, he joined Williams' podcasting business, Odeo. More interested in SMS technology than podcasting, Dorsey imagined a way for users to quickly share their status. In 2006, he proposed using SMS to send fast messages about a person's activity at a hackathon in his work. This idea became Twitter with the help of Glass and developed by Florian Weber.

Twitter was initially launched under the name 'twttr' in July 2006, inspired by Flickr and the five-character length of SMS short codes in the United States. This platform allowed users to post 140-character updates, reflecting the brevity of text messages. Dorsey's first tweet, 'just setting up my twttr,' marked the beginning of a new era in communication.

Just six months after launching Twttr, the team found the domain name twitter.com. They felt that this name was suitable for their idea, so they bought the domain name and renamed the service to Twitter.

Twitter grew rapidly, but CEO Dorsey struggled with management, leading to repeated system errors and employee dissatisfaction. By 2008, internal conflicts and pressure from Williams led to Dorsey being ousted as CEO and replaced by Williams, although Dorsey remained as chairman. Twitter continued to evolve, becoming a crucial tool for real-time news, social movements, and celebrity interactions. In 2011, Williams was removed and Dick Costolo became CEO. Dorsey returned in a more active role, eventually reclaiming the CEO position.

In November 2021, Dorsey resigned as CEO to prepare for the sale of Twitter. Parag Agrawal succeeded him briefly. Immediately afterwards, Elon Musk completed the acquisition of Twitter and renamed it 'X,' marking the end of an era. From 2006 to 2008 and from 2015 to 2021, under Dorsey's leadership, Twitter has evolved into a global communication tool but has faced challenges with freedom of speech, misinformation, and user privacy.

Apart from Twitter, Dorsey still wields influence through his work at Block (formerly Square) and his support for decentralized technologies like Bitcoin.

Change the name from Square to Block

Dorsey co-founded Square in 2009 with Jim McKelvey after losing a sale because he couldn't accept credit card payments. Seeing this as a major issue in payments, he founded Square to solve it.

Square's mobile credit card reader has democratized payment processing, allowing small retailers to compete with larger enterprises.

A major turning point came in 2013 with the launch of Cash App, now enabling peer-to-peer (P2P) payments, banking services, and Bitcoin transactions. In November 2015, Square held its first public offering (IPO) and raised $243 million, providing it with the necessary capital to continue its development.

Square Inc changed its name to Block Inc in December 2021 to better reflect its scope of offerings and belief in blockchain technology. "Block is a new name, but our goal of economic empowerment remains unchanged. No matter how we develop or change, we will continue to build tools to help enhance access to the economy," as Dorsey said in a press release.

Spiral (formerly Square Crypto), for the development of Bitcoin, Tidal for music streaming, Cash App for personal finance, Square for payment solutions, and TBD for decentralized operations, are all part of the Block ecosystem.
