Jainam and Jivika, siblings from Dubai who started their YouTube channel 'JJFuntime' in 2017, at the ages of 6 and 3, respectively, purchased the 'JioHotstar' domain from a Delhi-based techie. Initially, they made toy unboxing videos and eventually shifted focus towards science content. During their recent summer holidays, they left Dubai to spend 50 days interacting with kids in India.
