CBS aired this jazzy intro to NBA basketball games during the 1973–1976 and 1978–1979 seasons. Aki Lines, released in 1970, was a hot typeface at the time, appearing in all sorts of ads and branding for entertainment and high-tech products. It fits right in with the electro-glow animation accompanying these titles.
The line “You’ll see the best in basketball when you watch the NBA" in the theme song was a swipe at the American Basketball Association (ABA), which was still around at the time this theme music was written and recorded. — altfactor
