Vine shut down primarily because it was not monetizing effectively and could not sustain its operations under Twitter’s financial pressures and leadership changes. Over time, as competitors like Instagram and Twitter itself evolved, Vine lost both creator retention and audience engagement, making it costly to operate without a viable revenue model. Key factors:

• Limited monetization: Vine struggled to create sustainable revenue streams for the platform and its creators, which reduced long-term incentive to stay or invest in the app.

• Competition and feature gaps: Competitors added new features and larger user bases, drawing creators and viewers away from Vine. Vine’s six-second looping format didn’t evolve quickly enough to maintain relevance.

• Twitter’s finances and priorities: Vine depended on Twitter, whose own profitability and strategic resources were tightening, making continued support less feasible. This misalignment contributed to higher operating costs with diminishing returns.

• Creator churn and brand dynamics: The app saw high turnover among top creators who migrated to other platforms where monetization, sponsorships, and audience reach were stronger.
