Hateful images are making their way from niche sites onto popular social networks at an alarming speed. Here's how it works.
Effective political campaigns use three main online strategies; research identifies which of them is most effective.
Ugandan President Yoweri Museveni's grip on power remains strong but pockets of dissent are emerging from digital platforms.
Social media abhors informational vacuums and speed eclipses accuracy. That allows pseudo-experts, agitators and even liars to circulate rumours and poisonous information when big news breaks.
NFL players, historically losers in power struggles with team owners, can retake control of the kneeling-protest issue if they use social media to connect with the public.
