Advertising spending on the Indian Premier League (IPL), which includes TV and digital ads, has dropped by 20% due to the absence of some categories like betting, cryptocurrency and edtech, and a dramatic fall in viewership last year, said Viacom18 Sports' CEO Anil Jayaraj. He added that digital revenues were less affected as they were not dependent on certain categories. With the revenue mix having changed this year, the viewership on digital had a significant increase. The total advertising revenue for IPL this year has reportedly dropped to INR40bn ($536.8m) from INR40bn to INR50bn ($670m) last year.
