It shouldn't come as a surprise that women are the gender that dominate social media. Women love to talk, socialize and gossip, so naturally, they would be the ones more actively involved in the "social" aspect of social media.
The men, however, they sure dominate the visual aspect taking in the most viewers on YouTube. According to the Infographic below (I know, I can't help how much I love INFOGRAPHICS!), about 25% of men watch YouTube daily, compared with 17% of women.
In video streaming, women are not too far off, but clearly men are watching more and are much more active in the professional social media pages, such as LinkedIn.
This is really important information for marketing and targeting the correct demographic for your product.
