On March 13, 2010, New Jersey became the first Mega Millions participant (just before the cross-sell expansion) to produce a jackpot-winning ticket for Powerball after joining that game. The ticket was worth over $211 million annuity (the cash option was chosen). On May 28, 2010, North Carolina became the first Powerball member (just before the cross-selling expansion) to produce a jackpot-winning Mega Millions ticket after joining Mega Millions, with an annuity jackpot of $12 million.
The October 28, 2017 Mega Millions' format change resulted in the game's first price increase: plays are $2 each ($3 with the Megaplier; up from $1 and $2 respectively); as part of the format change, the "Just the Jackpot" option was introduced to seven of the game's members. The new option is two plays for $3; only the jackpot can be won (or shared) on this wager.
In 1998, Florida was given permission by its government to participate in a multi-state game. It was set to offer Powerball; but in early 1999, new governor Jeb Bush prevented Florida from joining since he believed Powerball would hurt the existing Florida Lottery games. In 2008, Governor Charlie Crist finally allowed Florida to join MUSL, on Jan 4, 2009.
Mega Millions' second-largest jackpot, $648 million, was for the December 17, 2013 drawing. Two winning tickets, one each from California and Georgia, were sold. The holder of the Georgia ticket claimed the next morning; they selected the cash option, which amounted to $173,819,742.50 before withholdings. The holder of the California ticket claimed on January 3, 2014. (The California ticket holder received an equal share, but potentially a larger cash-option amount, as California lottery winnings are exempt from state income tax)." 
The largest Mega Millions jackpot, advertised as $640 million at the time of the drawing (annuitized) or $462 million (cash value), was drawn on March 30, 2012. The initial estimate for that drawing (following the March 27 drawing, which was $363 million annuity) was $476 million (later increased to $500 million and again to $540 million); brisk ticket sales pushed the jackpot values, both annuitized (to $656 million) and the cash option ($474 million) higher. The amount spent on Mega Millions for drawings following its previous jackpot win, on January 24, 2012, was at least $1.5 billion. three jackpot-winning tickets had been confirmed (Illinois, Kansas, and Maryland).
Every jurisdiction has its own law on winners remaining anonymous. Some jurisdictions are required by law to provide the winner's name, city of residence, game won and prize amount to any third party that requests the information. Other jurisdictions allow winners to create trusts to shield their names from the public, or otherwise claim prizes anonymously. Check with your lottery to see if taking a photo of the winner is required and what its rules are on prize claims. Even if you keep your identity secret from the media and the public, you will have to be known to the lottery so officials can confirm you are eligible to play and win, as well as other legal requirements.
Unclaimed prizes are kept by the lottery jurisdiction. If a Grand Prize goes unclaimed, the money must be returned to all lotteries in proportion to their sales for the draw run. The lotteries then distribute the money, based on their own jurisdiction's laws, to other lottery games or to their jurisdiction's general fund, or otherwise as required by law.
State lotteries have become a significant source of revenue for states, raising $17.6 billion in profits for state budgets in the 2009 fiscal year (FY) with 11 states collecting more revenue from their state lottery than from their state corporate income tax during FY2009. Lottery policies within states can have conflicting goals. Given that instructions are passed down from state legislatures, lottery implementation is often expected to be carried out with reduced advertising and funding while still producing the same amount of revenue. This issue led states to look for loopholes in the system. Massachusetts, for example, had its advertising budget dramatically cut, and therefore started using free-play coupons as money to pay for advertising. This led to an IRS investigation into alleged non-reporting of income because the IRS considered the coupons to have monetary value.
Wednesday’s jackpot might have been the second-biggest, but many expected it to actually surpass that $1.6 billion record if that lucky Massachusetts ticket-holder hadn’t hit on the right numbers. That’s because of what Kelly Tabor, a spokeswoman for the Colorado Lottery, calls “jackpot chasers,” casual players who rush out to buy a ticket when the jackpot gets big enough.

This method specifically has faced criticism recently from a number of lottery organizers such as Camelot, the UK National Lottery organizers who are not happy with companies “selling tickets” (selling bets on outcomes of their established lottery draws) for prices sometimes even cheaper than Camelot themselves sells their tickets. This legal and corporate dispute looks set to continue for the foreseeable future, in the mean time you can continue to buy Powerball tickets online, only now you are aware of the key differences between the two business models.
