Facebook is being eclipsed by its youthful rival Snapchat

Social media giant struggles to stay relevant to a younger generation

Facebook has officially lost its cool. Snapchat is set to overtake it as the digital hangout of choice for teens and twentysomethings this year, as Mark Zuckerberg's social media site struggles to remain relevant to the youth generation.

By the end of this year Snapchat, which with its disappearing messages and funky photograph filters has already won over young teens, will also become the most popular social media platform in the UK for 18- to 24-year-olds.
