LA glitz or Indy's legendary races? Which city is the true epicentre of American sport

The title of "true centre" of American sport is as much a debate about culture as about the economics of the sport. The new HistoryExtra programme sets up the two extreme points of that debate against each other: Los Angeles and Indianapolis. At first sight this is an uneven comparison; the real comparison point is structural rather than numerical.
Los Angeles has a strong numerical anchor. The city hosts a large share of America's professional major-league families: NBA (Lakers, Clippers), NFL (Rams, Chargers), MLB (Dodgers, Angels), NHL (Kings, Ducks), MLS (Galaxy, LAFC). It is also the host city of the 1932, 1984 and 2028 Olympics.
What sets Los Angeles structurally apart is not only the number of teams. The city defined the "star economy" model of American sport. Magic Johnson's draft to the Lakers in 1979 accelerated mainstream American sport's cycle of identifying star players with the city. That cycle ran on through Kobe Bryant, Mike Trout and into the modern era of LeBron James.
Indianapolis's counter-argument sits on a different structural axis: motorsport. The Indianapolis Motor Speedway was built in 1909; within two years the Indianapolis 500 had become one of the most-watched single-day sporting events in the world. The city is also the home of the national automotive engineering follow-up bodies.
Indianapolis also hosts the headquarters of the NCAA, the structural centre of college sport in the US. The NCAA has been headquartered in Indianapolis since 1999. That fact is numerically invisible but structurally large: in US sports culture, college sports (football, basketball) make up a significant share.
Culturally, the two cities represent different models. Los Angeles invented the Hollywood-sport partnership: the player steps off the bench and into stage lighting. Indianapolis rests on an engineering culture, the tradition of hard-traction racing and an identity that keeps the city's ethnic choreography inside the old industrial frame.
Socio-economic data set the two cities' roles in the sports economy apart. The Los Angeles metropolitan area accounts for roughly 11% of the US sports market; Indianapolis sits around 3-4%. Even so, Indianapolis's per-capita count of Olympic training centres is above the national average.
Their historical winning records take different shapes. Los Angeles teams have won about 39 mainstream professional championships (with Lakers, Dodgers and LA Galaxy at the front); Indianapolis carries an 11-title balance once the Pacers, Colts and Indiana University share are added together. By numbers Los Angeles is ahead, but raw number alone is not enough for comparison.
The third category that matters for the choreography of culture is birthplace. The Indianapolis basketball coach Bobby Knight at Indiana University shaped the core structural architecture of the NCAA. Los Angeles defined the modern social-media-based athlete brand economy; athletes such as LeBron James, Carmelo Anthony and Serena Williams built their media strategies in partnership with the city's film studios.
The HistoryExtra summary highlights the difficulty of trying to pin the term "epicentre" on a single city. Los Angeles defines the commercial economy and star system of sport; Indianapolis embodies the engineering culture, the college ecosystem and the endurance-sport traditions of sport. For American sport, these two cities perform complementary structural functions, and calling either of them the "true centre" alone falls short historically.
