There are around 144 million active adblock users worldwide, with growth of nearly 70% between 2013-2014. Adblocking usage varies by country and is highest among 18-29 year olds. Native advertising is a form of paid media that follows the natural form and function of user experience, and spent $4.3 billion in 2015. Content marketing involves communicating with customers through storytelling without direct selling, using types of content like blogs, videos, and reports. It differs from native advertising in that its goal is long-term trust-building rather than immediate sales.
