Crowdfunding has become a major source of funding for video game development. Games that aimed to raise $150 in 2009 were able to raise $2000, showing how crowdfunding has grown over time. The largest crowdfunding platform, Kickstarter, has helped raise over $1.19 billion for more than 21,000 successful video games. Social media plays a key role in marketing games and helping previously niche games reach broader audiences. Traditional physical distribution of games in stores has been replaced by online distribution through subscriptions and in-app purchases.
