YouTube announces two new features for the end of 2010 - algorithm-powered YouTube Trends and The Year in Review, which will use the new Trends product to feature demographically popular submissions.

The Holiday Season typically differentiates itself with the lion's share of gift promotions, new products, and reflections upon the previous year. This time around, each news site seems to have its own best, worst or most "somethings" of 2010. No different is YouTube, which has a new product, YouTube Trends, and a new crop of videos for its TheYearInReview Channel.

YouTube Trends gives site users another way to keep current on which videos are going viral in real time. The Trends tool is similar to those of other social media sites, such as Twitter, and uses algorithms to highlight "trending videos and topics." For example, this afternoon the Trending Topics include "Michael Jackson Akon Hold My Hand," "Dolphin Dolphins," "Minnesota Vikings Metrodome." These topics are generated from algorithms that identify keywords in the title, description or tags of a submission.

The new product curates a "4 at 4" twice daily from trends feeds and from "top video curation sites around the web." Once at 4AM and once at 4PM Eastern time, the site identifies "four of the videos generating significant buzz on YouTube and on news and culture websites." This appears on the site as well as on a dedicated YouTube Trends blog, along with a dashboard that gives users popularity according to location (city or country) and other demographic sets.

Different from the "Most Viewed" videos on the main YouTube site, Trends uses different types of algorithms that measure popularity "in different and more experimental ways as compared to our browse pages."

Trends was announced at the same time as YouTube's TheYearInReview Channel, which will be populated based on the findings of the Trends product. According to YouTube Trends Manager Kevin Alloca, in the next twelve days, Trends will analyze most viewed videos in categories such as "news and politics, sports, and trailers."
