Here's what Irish people engaged with on the internet in 2015

The same-sex marriage referendum, Ed Sheeran and miniature Guinness cakes were just some the most viewed and talked about videos and issues Irish people engaged with this year.

Social media giants YouTube and Facebook both released the country’s most watched, shared, and talked-about videos and topics for the past year.

This year was the year for powerful global and national campaigns. On Facebook, the same-sex marriage referendum was the most talked-about topic, followed by the Syrian Civil War and refugee crisis and St Patrick’s Day.
