As Investopedia charts its course as a media brand, it’s coming up against the roadblock all publishers eventually hit — the reality that display revenue alone won’t be enough. Investopedia joins a league of media companies that have been exploring new ways to generate revenue beyond editorial content, including fee-based premium services and other products. Building off its niche in finance and investing, IAC-owned Investopedia Tuesday launched its own financial education academy with on-demand courses. To the company, the educational space is a good fit because competitors don’t focus on finance, and Investopedia can organically generate interest based on the strength of the brand. David Siegel, the company’s CEO, said future plans for the school include an online MBA, in conjunction with an educational institution.
