They made us laugh and cry but they definitely provoked an emotion!
It's probably time to admit that without viral videos, our lives would be so much duller.
Viral is a media term that grates against most people but these videos from 2015 certainly fall into the category of viral. They made made us laugh, they made us cry and they were everywhere.
Here's our top ten.
1. DON'T SWIM IN THE SEA
Just recently, the biggest viral video of the year made an appearance. Teresa Mannion, coming from storm torn Salthill nearly blew away and had the entire country in convulsions.
2. The Heartbreaker
There were many Christmas adverts this year that broke our hearts but this was most certainly top of the list. His own funeral!
3. Marty McFly and Doc Brown
In Back to the Future, the year Marty McFly travelled to was none other than 2015. Celebrations everywhere.

11. Jimmy Kimmel Mean Tweets
The Obama edition of Mean Tweets easily made it into one of the most viral videos of 2015.

During the Marriage Referendum, we saw quite a number of heartfelt pleas for people to Vote Yes. This was one of the most beautiful.
13. Celebrate Good Times
Galway hurling. We'll say no more.
14. Parody Central
Drake released this video for Hotline Bling. Within hours, there were parodies everywhere. Literally everywhere.
15. The Depp

And here's a collection of some of those videos:
