We've officially wrapped up a big year for the genre we all love-- new albums from Jay Z, Kanye West, Pusha T, Mac Miller, Drake, Juicy J (and the list goes on), only made 2013 that much sweeter. Mix in a new-found competition brought on by, you guessed it, "Control," and all the free mixtapes we've received in 2013, and this past year was definitely a good one.

Apart from the usual rap antics, 2013 was significant as it marked 40 years since hip-hopâs inception, starting out in the Bronx borough of New York City and spreading across the world. Now that we entered a new year, we've decided toÂ take a look back at some of the biggest moments throughout the last four decades of hip-hop.

In celebration of the genre's prevailing legacy, weâre looking at each of the four elements of hip-hop culture: rapping, DJing, graffiti, and breaking.

Enjoy and spread the knowledge!
