"The Patriots time in the AFL saw them struggle most years as they never had a regular home stadium. (what great fan support, eh? ) Nickerson Field, Harvard Stadium, Fenway Park, and Alumni Stadium all served as home fields during their time in the American Football League. They did play in one AFL championship game, following the 1963 season. They lost to the San Diego Chargers 51–10.They would not appear again in an AFL or NFL post-season game for another 13 years. (Pathetic, eh?)
When the NFL and AFL merged in 1970, the Patriots were placed in the AFC East division, where they still play today. The following year, the Patriots moved to a new stadium in Foxborough, Massachusetts, which would serve as their home for 30 years. As a result of the move, they would change their name from the Boston Patriots to the New England Patriots.
During the 1970s, the Patriots had some success, earning a berth to the playoffs in 1976—as a wild card-berth—and in 1978—as AFC East champions. They would lose both games. In 1985, they returned to the playoffs, and made it all the way to Super Bowl XX, which they lost to the Chicago Bears 46–10. Following their Super Bowl loss, they returned to the playoffs in 1986, but lost in the first round.
The team would not make the playoffs again for eight more years. They changed ownership several times, being purchased from the Sullivan family first by Victor Kiam in 1988, who sold the team to James Orthwein in 1992. Orthwein intended to move the team to his native St. Louis, Missouri, but sold the team two years later to current owner Robert Kraft in 1994."
