Transcript for Powerball fever grows as jackpot reaches $750M
An estimated $750 million are up for grabs in the Powerball drawing tomorrow night. Just a few days after that billion dollar jackpot. T.J. Holmes is here and, T.J., these big jackpots seem like the new norm. Don't get T.J. Out of bed for less than a billion dollars, okay. We just had a $1.5 billion jackpot. Now 750 million, I mean, can you even live off that? Look, yes, it seems like the new Normal, so what's happening? What's happening is exactly what lottery officials designed to happen. Saturday's Powerball drawing of $750 million could potentially be the fourth biggest jackpot in U.S. History. I feel luck. $750 million is worth a try. Reporter: But on the heels of the $1.5 billion mega millions jackpot just three days ago, 750 million might seem, eh. But still enough to purchase this, the most expensive home on the market could be yours for $245 million. A huge lottery jackpot seemed to be the new Normal and it's no fluke. Rumor has it they changed the game, changed the rules. Reporter: Back in 2015 Powerball changed the odds of winning from 1 in 175 million to 1 in 292 million and last year mega millions followed suit decreasing the odds from 1 in 259 million to 1 in 302 million. That means jackpots get bigger and bigger and bigger leading ticket sales to skyrocket. When it gets above 500 million, it's like, oh, I should -- why not. Yeah, why not? Mega millions changed their odds just in October. In the past 12 months three out of the largest six mega millions jackpots of all time have happened. I had always used that $500 million excuse. I never realized how dumb it sounds. But here's the next problem is now there's going to be a new threshold. Now it used to be 500 million. Now it'll be a billion for some people and get this same fatigue. What changed to make it harder? Manipulated the number of jackpot balls in the bin. You take one out, you change the numbers and change the combinations in there and increases your odds of getting a smaller prize, but to get the jackpot -- It is nice you're getting more $1 million winners, like 26 or 38 in that last one. That is great if you want to go with some logic. Here are two things, George is now going to lower his threshold. No. Don't wake T.J. Up for under a billion dollars. The new threshold. A billion.
