The Chamber undertook an ambitious expedition called “California on Wheels.” A railroad car outfitted with agricultural products of the state visited every town of importance in the Midwest and South.

Frank Wiggins, the superintendent of events, conceived of the idea and pushed to feature California agricultural products at large national and international exhibitions; attracting nationwide fame to Los Angeles.

The chamber attracted aircraft manufacturing in 1920 through its support of international air meets at Dominguez field and communication of meteorological information that made flights safer for pilots.

The local livestock market received a boost when the Chamber collaborated with Chicago entrepreneurs in 1921 to create an area called the Central Manufacturing District and Los Angeles Junction Railway.

After World War II, the Chamber transitioned from organization that sought to attract new business to Los Angeles County into one that now worked to address modern issues associated with a major metropolitan center.

Despite a business exodus from Downtown Los Angeles since the COVID-19 pandemic, the city's urban core is evolving as a cultural center with the world's largest showcase of architecture designed by Frank Gehry.
