Now, newsjacking has been around for ages and charities have been taking advantage of trending hashtags, or news, in both good and bad ways – mostly good.
Recently, I’ve noticed one charity that seems to have nailed it.
They have clearly thought their key messages through and they are reaping the benefits – their latest one, which focussed on the news story that skinny jeans could be bad for your health (oh dear, Hipsters) had 74 Retweets.
So who is it?
Here’s one for National Kissing Day.
But best of all? These ones for Game of Thrones.
I think these are wonderful examples of how to take advantage of trending hashtags, in a meaningful way. Have you spotted any others?
