Cats, Felix Baumgartner, Psy and more cats -- this week's most popular and iconic videos feature everything from the inspiring to the adorable to the hilarious.
Google compiled a Year In Review video posted on December 12. The nearly three-minute clip starts with Baumgartner's jump from 24 miles above the earth and progresses into clips of other history-making moments this year: Oscar Pistorius' competing in the Olympics as the first athlete to have carbon-fiber artificial legs; clips from this year's presidential debates; images from the Arab Spring and the protests in Greece, plus some adorable animal videos that kept us entertained.
Mashable's video compilation also adds more clips and images that are also gaining traction on the social web: An adorable blind cat names Oskar shows he can navigate his way down a cat tree, and a fluffy cat shows his owner he understands how to get attention.
Videos and images that end up going viral on the web document anything from silly cat antics to major political movements.
