Question: When did the drinking age become 21 in the state where My Talk Show is located?

full_context: Document 1: Cheers: Early discussions about the location of the show centered on Barstow, California, then Kansas City, Missouri. They eventually turned to the East Coast and finally Boston. The Bull & Finch Pub in Boston, which was the model for Cheers, was chosen from a phone book. When Glen Charles asked the bar's owner, Tom Kershaw, to shoot exterior and interior photos, he agreed, charging $1. Kershaw has since gone on to make millions of dollars, licensing the pub's image and selling a variety of Cheers memorabilia. The Bull & Finch became the 42nd busiest outlet in the American food and beverage industry in 1997. During initial casting, Shelley Long, who was in Boston at the time filming A Small Circle of Friends, remarked that the bar in the script resembled a bar she had come upon in the city, which turned out to be the Bull & Finch.

The program became a hit with viewers, leading to the series being picked up for syndication. The shows' setting took place in Bass' home with the garage being converted into an area for the studio audience, since the local television station in Bass' home town (possibly Milwaukee, since a channel 65 was circled as the station in the credits that showed a newspaper TV listings that also featured actual TV channels from Madison, Rockford and Chicago) could not accommodate any space for the production, so a satellite van and cameras were bought over to help tape the show for the airing.

Document 6: The Wright Stuff: It has been a feature of the show that there is a female co-host (originally a telephone operator) in a booth separated from the main presenter and guest area.

Document 10: U.S. history of alcohol minimum purchase age by state: From 1976 to 1983, several states voluntarily raised their purchase ages to 19 (or, less commonly, 20 or 21), in part to combat drunk driving fatalities. In 1984, Congress passed the National Minimum Drinking Age Act, which required states to raise their ages for purchase and public possession to 21 by October 1986 or lose 10% of their federal highway funds. By mid-1988, all 50 states and the District of Columbia had raised their purchase ages to 21 (but not Puerto Rico, Guam, or the Virgin Islands, see Additional Notes below). South Dakota and Wyoming were the final two states to comply with the age 21 mandate. The current drinking age of 21 remains a point of contention among many Americans, because of it being higher than the age of majority (18 in most states) and higher than the drinking ages of most other countries. The National Minimum Drinking Age Act is also seen as a congressional sidestep of the tenth amendment. Although debates have not been highly publicized, a few states have proposed legislation to lower their drinking age, while Guam has raised its drinking age to 21 in July 2010.
