#2 Neymar
As the Pele of his generation, it'd be remiss of Neymar not to be a social media addict. With 70 million Instagram followers, 59 million fans on Facebook and 27 million followers on Twitter, the Brazilian truly does have a gigantic audience to cater for.
At one point Neymar got so addicted to posting online that Barcelona officials had to ask him to calm down on his frequency of posting. However, back then it was seen as an embarrassment to be so active on the internet, now it's seen as marketing & branding. On average, the Brazilian posts 24 times a day.
Neymar was one of the first footballers to turn their social media activity into a marketing tool. Not only does he promote himself but he also uses his mass following to champion certain charitable programs. This kind of influence can spread awareness of growing problems in the world.
The 25-year old is a prime example of how powerful constant social media posting can be.
