"The Same Picture of Dave Coulier Every Day" is an image blog which publishes the same photograph of Coulier every day. Begun in 2011 by comedian Aaron Littleton, it is the progenitor of a trend of similarly themed blogs which feature the same content in every daily update. The trend of such "content homogeneity" has been studied in academic literature. The trend has also been called "single-topic", and Forbes has called The Same Picture of Dave Coulier Every Day the apotheosis of the movement.
