The 'Impact' meme style, characterized by bold white text with a thick black outline, defined the visual language of the internet during the late 2000s and early 2010s. Utilizing the Impact typeface designed by Geoffrey Lee, this format became the gold standard for 'Advice Animal' memes like Bad Luck Brian and Success Kid. It typically follows a two-part joke structure: a setup at the top and a punchline at the bottom. While internet culture has evolved to include many different aesthetics, the Impact style remains the most universally recognized meme format, symbolizing the birth of modern viral humor and the era of image macros.
