At 4:24 p.m. (GMT) today, Duchess of Cambridge Kate Middleton and Prince William welcomed their newborn baby boy into the world. During Middleton's approximately 10 hours of labor, the internet became abuzz with predictions about the future heir's name and birth time, along with several trending Twitter hashtags like #GreatKateWait, #RoyalBabyWatch and #RoyalBaby. Tens of thousands of people flocked to online betting sites to wager on the baby's name and weight, raising the stakes to nearly £1 million (appx. $1.5 million USD) by some estimates.
