Problem Description

Chen, Adrian (November 7, 2013). “Doge Is An Ac- tually Good Internet Meme. Wow.”. Gawker. Retrieved November 22, 2013.

Doge is an Internet meme that became popular in 2013. The meme
typically con- sists of a picture of a Shiba Inu dog ac- companied by
multicolored text in Comic Sans MS font in the foreground. The text,
representing a kind of internal monologue, is deliberately written in
broken English, and usually contains the word “wow” and the phrases
“such x”, “much x”, “many x”, “very x” and “so x”.
Kabosu, the
Shiba Inu featured in the original meme, was first pictured in a 2010
blog post by Atsuko Sato, a Japanese kindergarten teacher. Afterwards,
varia- tions of the pictures using overlaid Comic Sans text were posted
from a Tumblr blog, Shiba Confessions. However, the use of the
intentionally misspelled “doge” dates back to June 2005, when it was
mentioned in an episode of Homestar Runners puppet series.
In
August 2013, images of the meme were spammed on Reddit’s r/MURICA
subreddit by 4chan’s random imageboard, /b/. A search of the term doge
on Google Trends shows an explosion of popularity occurring in October
2013, and more so in the following month. By November 2013, the meme had
become widespread on the Internet. Google later created a Doge Easter
egg: when doge meme was entered into the YouTube search bar, all of the
site’s text would be displayed in colorful Comic Sans, similar to the
kind used by the meme.
The meme was ranked #12 on MTV’s list of
“50 Things Pop Culture Had Us Giving Thanks For” in 2013. Io9 compared
the internal dialog of the Shiba Inu dogs to lolcat-speak. The image
most commonly associated with the meme is of a female Shiba Inu named
Kabosu, taken from a Japanese blog documenting the dog’s daily
activities. The spelling of doge has several variants, leading to debate
on its actual pronunciation. On December 13, Doge was named the “top
meme” of 2013 by Know Your Meme.
In December 2013, the Dogecoin
was introduced as a new cryptocurrency, making it the first
cryptocurrency to be based on an Internet meme; the viral phenomenon,
along with usage of the Comic Sans MS typeface, gave it “the Internet
density of a large star” according to Medium writer Quinn Norton.
In
late December 2013, members of the U.S. Congress produced material in
the meme’s style. Huffington Post commented that Doge was “killed”
because of the Congress members’ usage of the meme.
By early 2014,
Doge’s popularity was sustained by internet communities on social
media, accompanied by the rapid growth and acceptance of Dogecoin. In
April 2014, Doge experienced a second major media resurgence due to
revelations of the Dogecoin community’s intent to sponsor Josh Wise in
NASCAR and place a picture of the Shiba Inu on his vehicle.
