The St. Louis Browns, who had played in Milwaukee in 1901, the inaugural season of the American League, applied for permission to relocate back to the city they had left half a century before.

Three weeks before the beginning of the 1953 season, and right before the new stadium was ready to open, the Braves made it official, applying for permission to relocate.

The first published issue of Sports Illustrated on August 16, 1954, featured County Stadium with Braves batter Eddie Mathews on its cover, along with New York Giants catcher Wes Westrum and home plate umpire Augie Donatelli.

The stadium continued to be the National League's top draw until 1959 when the Dodgers, who had moved to Los Angeles two years before, overtook the Braves (both in the stands and on the field).

The Milwaukee Braves used the stadium through the 1965 season when new owners, seeking a larger television market, moved the team to Atlanta.

In light of this success, Selig and Allyn agreed that County Stadium would host Sox home games again the next season.

Those games took place on April 23 vs. the California Angels,[25] May 22 vs. the Detroit Tigers,[26] May 28 vs. the New York Yankees,[27] June 11 vs. the Cleveland Indians,[28] June 16 vs. the Seattle Pilots (who eventually became the Brewers the next season),[29] July 2 vs. the Minnesota Twins,[30] July 7 vs. the Oakland A's,[31] August 6 vs. the Washington Senators,[32] August 13 vs. the Boston Red Sox,[33] September 1 vs. the Baltimore Orioles,[34] and September 26 vs. the Kansas City Royals.

The new Milwaukee Brewers, named for the American Association club for which County Stadium was originally built over 20 years earlier, called it home from 1970 to 2000.

Aaron's final home run took place in the 7th inning with a solo shot off California Angels right-hander Dick Drago on July 20, 1976, a game that the Brewers would win 6–2.

By the 1990s, County Stadium was considered outdated, lacking the amenities (most notably luxury boxes) that generated additional revenue for teams.

On July 11, 1992, Selig announced plans for a publicly financed replacement to be built adjacent to County Stadium, opening in time for the 1994 season.

Miller Park's most distinctive new feature was a retractable roof, deemed essential to drawing fans during the cool and unpredictable Wisconsin spring.

[43] The final major league game at County Stadium was on September 28, 2000;[44] Warren Spahn threw out the first pitch to Del Crandall, and also in attendance were Willie Davis, Hank Aaron, and Robin Yount.

After the game, there was a closing ceremony, where first home plate and the pitching rubber of County Stadium were removed, to be placed at Miller Park.

[54] The Packers' final game at County Stadium was a 21–17 victory over the Atlanta Falcons on December 18, 1994;[55] with fourteen seconds left, the winning 9-yard touchdown run was scored by quarterback Brett Favre, who was drafted by the Falcons in 1991 but traded the next year due to then-Atlanta coach Jerry Glanville's intense dislike of Favre.

[59][60][61][62][63] It was the first year that the NFL playoffs expanded to four teams, and Green Bay had home field advantage for both rounds, then awarded by rotation.

[68] Following the unsuccessful effort to lure the Packers to Milwaukee full-time, in 1965 city officials tried to lure an American Football League expansion team to play at County Stadium, but Packers head coach Vince Lombardi invoked the team's exclusive lease as well as sign an extension to keep some home games in Milwaukee until 1976.

[69] Nonetheless, city officials still pursued an AFL franchise, possibly to play at Marquette Stadium, but the AFL–NFL merger effectively quashed any chances of Milwaukee landing its own team.

Other musical stars who performed at County Stadium included Simon and Garfunkel, Pink Floyd, Crosby Stills & Nash, Fleetwood Mac, Jimmy Buffett, Kenny Loggins, Peter Frampton, Marvin Gaye, Al Green, The Jacksons, The Temptations, Smokey Robinson, B.B.

King, Emmylou Harris, Nancy Wilson, The Staple Singers, Archie Bell and the Drells, Frankie Avalon, the Hollywood Argyles, Johnny and The Hurricanes, James Brown, The Famous Flames, Lobo, Bread, Andy Kim, Gary Puckett, Rare Earth & The Honeycombs.

The series starred Craig T. Nelson as Hayden Fox, coach of the Orlando Breakers (a fictional NFL expansion team), from whose office window County Stadium can be recognized.

Also, in the film, fans in the stands are visible donning T-shirts bearing the name and logo of a local Milwaukee-area corporation, Quad Graphics (located in Sussex).

[84] On July 28, 1990, the United States men's national soccer team hosted an international friendly vs. East Germany,[85] losing 2-1.

[101] On May 1, 1975, Hank Aaron broke Babe Ruth's RBI record of 2211 by driving in his 2212th run at County Stadium as the Brewers beat the Detroit Tigers, 17-3.

On July 31, 1990, Nolan Ryan won his 300th Major League Baseball game at County Stadium when the Texas Rangers defeated the Brewers 11–3.

[104] On September 14, 1991, Cecil Fielder of the Detroit Tigers hit the only home run to sail over the outfield bleachers and completely out of County Stadium.

The Brewers closed out their tenure at Milwaukee County Stadium with an 8-1 loss to the Cincinnati Reds, a ceremony aired in full on both WTMJ Radio and Midwest Sports Channel.

[109] In a closing ceremony led by legendary announcer Bob Uecker, greats Braves, Brewers, and Green Bay Packers were introduced.

Brewers greats that came back to salute the fans and the stadium included Paul Molitor, Jim Gantner, Rollie Fingers and the widow of 1982 manager Harvey Kuenn.

When Uecker announced what would be the final player introduction in the stadium, he began, "his name is synonymous with the Brewers..." Robin Yount then appeared from the left field fence on another Milwaukee legend, a Harley Davidson motorcycle.
