LinkedIn has a near-monopoly on professional social networking. Founded in 2002 by Reid Hoffman and launched in 2003 from his living room in Mountain View, California, the platform now has over 1 billion members across 200 countries. Microsoft acquired LinkedIn in 2016 for $26.2 billion — at the time, Microsoft’s largest acquisition ever.
The platform serves multiple audiences simultaneously. Job seekers use it to find opportunities and build professional profiles. Recruiters use it to source candidates (LinkedIn Recruiter is a major revenue driver). Salespeople use it for lead generation (Sales Navigator). Marketers use it for B2B advertising. And increasingly, professionals use the feed to share industry insights, personal stories, and career advice.
LinkedIn’s revenue topped $15 billion in Microsoft’s fiscal year 2023, with income from three main segments: Talent Solutions (job postings, recruiter tools), Marketing Solutions (advertising), and Premium Subscriptions (LinkedIn Premium, Sales Navigator, LinkedIn Learning).
LinkedIn Learning, which came from the 2015 acquisition of Lynda.com for $1.5 billion, offers thousands of professional development courses. It’s become a common employee benefit at large companies.
The platform’s content feed has evolved significantly. What was once a fairly dry professional network now features a mix of industry articles, personal career stories, thought leadership, and yes, plenty of humble bragging and engagement-bait posts. LinkedIn’s algorithm heavily promotes content that generates comments, which has shaped the distinctive posting style the platform is known for.
For B2B companies, LinkedIn is essentially the only social advertising platform that reliably reaches business decision-makers. Its targeting capabilities — by job title, company, industry, seniority — are unmatched for professional audiences. This has made LinkedIn advertising expensive compared to other platforms but highly effective for the right use cases.
