Who created Doge Coin and when?

Dogecoin (/ˈdoʊ(d)ʒkɔɪn/ DOHJ-koyn or DOHZH-koyn,[2] Abbreviation: DOGE; sign: Ð) is a cryptocurrency created by software engineers Billy Markus and Jackson Palmer, who decided to create a payment system as a "joke", making fun of the wild speculation in cryptocurrencies at the time.[3] It is considered both the first "meme coin", and, more specifically, the first "dog coin". Despite its satirical nature, some consider it a legitimate investment prospect. Dogecoin features the face of the Shiba Inu dog from the "doge" meme as its logo and namesake.[4][5][6] It was introduced on December 6, 2013, and quickly developed its own online community, reaching a market capitalization of over $85 billion[a] on May 5, 2021.[7] As of 2021, it is the sleeve sponsor[b] of Watford Football Club.[8]
