Who is the founder of Twitter?
- (a)Jack Dorsey
- (b)Mark Zuckerberg
- (c)Fred Cavazza
- (d)John McCarthy
Correct — A, Jack Dorsey. Jack Dorsey is popularly credited as the founder of Twitter (launched 2006) — he wrote the initial project concept, posted the platform's first tweet ('just setting up my twttr'), and served as its first CEO. Twitter was actually built by a founding team of four — Dorsey along with Noah Glass, Biz Stone, and Evan Williams — but Dorsey is the individual most commonly credited and tested as 'the founder.'
- (b)Mark Zuckerberg — Co-founder and CEO of Facebook (launched 2004) — a different social-media platform, not Twitter.
- (c)Fred Cavazza — A French digital-strategy consultant and blogger known for commentary and infographics on the social-media landscape — not a founder of Twitter.
- (d)John McCarthy — An American computer scientist and pioneer of artificial intelligence — he coined the term 'Artificial Intelligence' and created the Lisp programming language; not connected to Twitter's founding.
Twitter (now X) was launched in 2006, created by a founding team at the podcasting company Odeo — Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams. Dorsey wrote the original concept and posted the platform's first tweet, and became Twitter's first CEO, which is why he is most commonly credited and tested as 'the founder.'
Tech-awareness questions on 'who founded X platform' typically want the single most publicly recognised name — for Twitter, that is Jack Dorsey, even though the platform had a multi-person founding team.
- Twitter (now X) launched in 2006; Jack Dorsey is its most commonly credited founder and first CEO.
- Twitter's founding team also included Noah Glass, Biz Stone, and Evan Williams.
- Mark Zuckerberg founded Facebook (2004) — a different platform.
- Jack Dorsey later returned as Twitter's CEO a second time (2015) before departing again in 2021.
- Confusing Twitter's founder with Facebook's founder (Zuckerberg) — both are frequently paired as distractors in tech-awareness questions.
- Mistaking a real but unrelated tech/computing pioneer (e.g. John McCarthy, an AI pioneer) for a social-media founder just because the name sounds plausible.
MPPSC/UPSC computer-awareness sets test 'who founded which tech platform' via simple recall or matching-pairs questions — anchor one name per platform (Dorsey↔Twitter, Zuckerberg↔Facebook, Wales↔Wikipedia, Brin↔Google Search).
Which of the following pairs is/are correctly matched? 1. Francis Collins — Mapping human genome 2. Sergey Brin : Google Search Engine 3. Jimmy Wales — Wikipedia Select the correct answer using the code given below:
- (a) 1 and 2 only
- (b) 2 and 3 only
- (c) 3 only
- (d) 1, 2 and 3
Answer(d) 1, 2 and 3
Same concept — matching a named tech figure to the internet service they are credited with founding; UPSC 2008 tests Sergey Brin↔Google Search Engine (and Jimmy Wales↔Wikipedia), this question tests Jack Dorsey↔Twitter.
