The couple would have lost the money on the next question anyway...so it is fair that they have a second chance....they shouldn't just be given the 800,000dollars

Absoloutly crazy you can tell they made a mistake as soon as you saw the money drop

New Show Million Dollar Drop Screwup

3M oughta know and they said so
so Million Dollar Money Drop was right
so that couple shouldn't get the money

The question must be settled in court.there is no other way to solve the problem because various information sources seem to indicate different dates.And if I was the couple yes I'd sue,or possibly ask to come back on the show and/or take a settlement.

History (Wikipedia)
In 1968, Dr. Spencer Silver, a chemist at 3M in the United States, accidentally developed a "low-tack", reusable, pressure sensitive adhesive.[1] For five years, Silver promoted his invention within 3M, both informally and through seminars, but without much success. In 1974, a colleague of his, Art Fry, who had attended one of Silver's seminars, came up with the idea of using the adhesive to anchor his bookmark in his hymnbook.[2][3] Fry then developed the idea by taking advantage of 3M's officially sanctioned "permitted bootlegging" policy.[3] 3M launched the product in 1977, but its results were disappointing.[4] A year later, 3M issued free samples to residents of Boise, Idaho, and 95 percent of the people who tried them said that they would buy the product.[4] By 1980, the product was being sold nationwide in the US; in 1981 Post-its were launched in Canada and Europe.[5]

In 2003, the company came out with Post-it Brand Super Sticky notes, with a stronger glue that adheres better to vertical and non-smooth surfaces.[6]

Standard Post-it Brand notes have only partial adhesive coating on the back, along one edge. Similar products are used for specialized purposes with full adhesive coating; the US Post Office uses such yellow address labels to forward mail.

The yellow color was chosen by accident; a lab next-door to the Post-it team had scrap yellow paper, which the team initially used.[7

A good or service must be proven to be available for commerce before it can be Trademarked. The US Trademark Office shows 'Post Its' were first Trademarked on 1974-09-25 and therefore available for purchase.

Let's be honest. Post-Its-gate is the only interesting about this game show. Total snooze.

PRODUCER OF MILLION DOLLAR DROP IS CORRECT

Local research shows Silver & Fry made these removable bookmarks for use in their own offices, before convincing executives at 3M's headquarters to try using them in 1977. 3M finally began test marketing "Press 'n' Peel pads" in 1978, and after two more years of market research, the product was formally introduced into American stationery stores as "Post-It notes" on 6 April 1980. Silver filed 22 patents in his career at 3M, and the same adhesive used in Post-Its has been adapted to other products from medical bandages to interior-decorating kits, but he never received any royalties, and retired from 3M in 1996.
