We'd give you chocolates with it if we could: This week marks the launch of our advent-style calendar counting down some of the most memorable videos of the year on YouTube. This sponsored collection, presented by Samsung U10, will reveal one new popular video each day throughout the month of December.

Without giving too much away, you can expect to see some well-known YouTube videographers on the countdown, along with breakout viral videos and a selection of the year's biggest pop-culture phenoms and memes.

During December, we'll be adding playlists to the channel to dig a little deeper into YouTube's content categories -- because we know that a video doesn't have to have millions of views to make an impact.

So check out the countdown as it unfolds, and see if your favorite clips or personalities are featured. Definitely let us know in the comments what your video of the year would be, whether it's a blockbuster clip or one that simply made an impression on you. With a limit of 31 videos in the countdown, we know it only just scratches the surface of this incredible time on YouTube.
