 ESPN's "Sunday Night Football" games would become the highest-rated NFL telecasts for the next 17 years (before losing the rights to NBC in 2006).The channel's decision to broadcast NFL games on Sunday evenings actually resulted in a decline in viewership for the daytime games shown on the major broadcast networks, marking the first time that ESPN had been a legitimate competitor to NBC and CBS, which had long dominated the sports television market.In 1992, ESPN launched ESPN Radio, a national sports talk radio network providing analysis and commentary programs (including shows such as "Mike and Mike in the Morning" and "The Herd") as well as audio play-by-play of sporting events (including some simulcasted with the ESPN television channel).
