Remember this moment because it probably won’t last: A U.S. lottery jackpot is projected to soar above $1 billion, and that's still a big deal. Friday’s Mega Millions drawing is worth an estimated $1.15 billion. The prize has evoked headlines across the country, despite the nation's top 10 jackpots already having boasted billion-dollar payouts. Jonathan Cohen is the author of the book “For a Dollar and a Dream: State Lotteries in Modern America.” He says he expects jackpots to continue to grow in size. Larger payouts attract more media attention, increase ticket sales and bring in new players.
