full_context: Document 1: Slime Time Live: Slime Time Live is a television series that aired on Nickelodeon from 2000–2003, lasting 8 seasons. During its run it was hosted by Dave Aizer, Jonah Travick and Jessica Holmes and produced/directed by Jason Harper.

Document 2: Beanie Babies: Nine original Beanie Babies were launched in 1993: Legs the Frog, Squealer the Pig, Spot the Dog, Flash the Orca, Splash the Whale, Chocolate the Moose, Patti the Platypus, Brownie the Bear (later renamed ``Cubbie ''), and Pinchers the Lobster (with some tag errors with`` Punchers''). They were not in factory production until 1994. Sales were slow at first to the point that by 1995 many retailers refused to buy the products in the bundles Ty offered them while others outright refused to buy them in any form. Their popularity soon grew however, first starting locally in Chicago before growing into a national craze in the USA.

Document 11: History of Nintendo: In 1966, Yamauchi was observing a hanafuda factory. He noticed an extending arm, which was made by one of their maintenance engineers, Gunpei Yokoi, for his own amusement. Yamauchi ordered Yokoi to develop it as a proper product for the Christmas rush. Released as the ``Ultra Hand '', it would become one of Nintendo's earliest toy blockbusters, selling over a million units. Seeing that Yokoi had promise, Yamauchi pulled him off assembly line work. Yokoi was soon moved from maintenance duty to product development.
Document 12: Kinder Surprise: In 1997, the staff of the Consumer Product Safety Commission (CPSC) examined and issued a recall for some Kinder Surprise illegally brought into the US with foreign labels. The staff determined that the toys within the eggs had small parts. The staff presumed that Kinder Surprise, being a chocolate product, was intended for children of all ages, including those under three years of age. On this basis, the staff took the position that Kinder Surprise was in violation of the small parts regulation and should be banned from importation into the US.
Document 13: Grover: A prototype version of Grover appeared on The Ed Sullivan Show in a Christmas Eve appearance in 1967. This puppet had greenish - brown fur and a red nose. He also had a raspier voice, and was played a bit more unkempt than Grover would later behave. The monster was referred to as ``Gleep '', a monster in Santa's workshop. He later made a cameo appearance in The Muppets On Puppets in 1968 with the Rock and Roll Monster. In 1969, clad in a necktie, he appeared in the Sesame Street Pitch Reel in the board room sequences. During the first season of Sesame Street, the character was nicknamed`` Fuzzyface'' or ``The Hairy One '', though neither would be used for his actual name. In his book The Tipping Point, author Malcolm Gladwell notes that the character`` was used in promotional films for IBM.''
Document 14: Post-it Note: In 1968, Dr. Spencer Silver, a scientist at 3M in the United States, was attempting to develop a super-strong adhesive. Instead he accidentally created a ``low - tack, ''reusable, pressure - sensitive adhesive. For five years, Silver promoted his`` solution without a problem'' within 3M both informally and through seminars but failed to gain acceptance. In 1974 a colleague who had attended one of his seminars, Art Fry, came up with the idea of using the adhesive to anchor his bookmark in his hymn book. Fry then utilized 3M's officially sanctioned ``permitted bootlegging ''policy to develop the idea. The original notes' yellow color was chosen by accident, as the lab next - door to the Post-It team had only yellow scrap paper to use.
Document 15: Norev: According to the official website, Norev was founded by the Véron brothers, in the suburb of Villeurbanne, near Lyon, France, in 1946 (Rixon 2005, p. 54).

In 1953, after the first plastics toy fair in Oyonnax, Joseph Véron started using the new plastic 'Rhodialite' for a series of toys (Ralston 2008, p. 25). The company's first product was a small tin service garage with several plastic cars in about 1/87 scale. Other products at the company's start were toy watches, miniature sewing machines, a doll's feeding set and other plastic toys for infants (Ralston 2008, p. 25).
