1971's 'Chicano I & II' was the first time a commercial TV network focused on people of color in US. Now it's revived
“Chicano I & II: The Mexican American Heritage Series” aired on KNBC-TV in July of 1971 and examined history from the Chicano perspective. The program reran once in 1972, then the film reels remained untouched in a garage for 50 years. Now the show’s original host and USC have revived nine of the 20 episodes for the public to view.
