My sister and I go in on tickets whenever the jackpots get big. We just buy one ticket.
Thanks to the increase of the number of balls they use, it now takes much longer to get a winning ticket so the jackpots get huge. It's possible the jackpot could get to two or even three billion if nobody wins for another few weeks or months.
And actually, lotteries are older than America itself. There are ads in Colonial newspapers for lottery tickets!
