The Adrien Broner vs Shawn Porter fight drew in an overnight rating of 1.8 average viewers Saturday night from the MGM Grand in Las Vegas, NV. The rating equalled to around 2.38 million viewers, which is the lowest of the three PBC on NBC primetime events. The fight peaked at around a 2.5 rating making it just around the 3 million mark for the number of viewers watched. The numbers aren't bad but they have consistently gone down since the debut of the PBC four months ago. The fact that it's summer time could be part of the problem. Boxing has never had a great amount of viewers in the summer months. June, July, and August are usually slow for all sports in the United States. The ratings was an overnight rating and could be much higher when the final numbers are in.
