“Baby Shark (Doo Doo Doo Doo Doo Doo)” is the YouTube sensation that’s been viewed more than 2 billion times and made the Billboard Hot 100 chart for a second-straight week. The jingle has also become such an earworm that late-night-show host Jimmy Kimmel proposed throwing those responsible in jail for life. Love or hate it, the South Korean company behind the one-and-a-half minute song about a family of sharks is now seeking to capitalize on the success by expanding its kid-oriented entertainment business.
