at that time. According to an analysis published by Barron's Magazine in February 2008, ESPN "is probably worth more than 40% of Disney's entire value... based on prevailing cash-flow multiples in the industry." Despite it technically being a joint venture, for all intents and purposes, ESPN operates as a division of Disney as a result of the company's controlling interest (as it was with ABC and Capital Cities before it). On July 15, 1985, ESPN started airing the "ESPN Sports Update" (later known as the "28/58 Update"), a condensed rundown of scores and news that aired at 28 and 58 minutes past the hour at times when SportsCenter was not airing. Later, when the viewers were used to it, the updates would often start with a sponsor where it used to say "28/58 Update" and the vertical display of "Update". The airtimes of these updates were modified to 18 and 58 minutes past the hour on May 30, 2005. In 1987, ESPN gained partial rights to the National Football League. The league agreed to the deal, as long as ESPN agreed to simulcast the games on broadcast television stations in the local markets of the participating teams. ESPN Sunday Night Football would last for 19 years and spur ESPN's rise to legitimacy. During the 2006 NFL season, ESPN began airing Monday Night Football, formerly seen on its sister network ABC (NBC took over broadcast rights to the Sunday night game package). Former Commissioner Paul Tagliabue credits ESPN for revolutionizing the NFL: "ESPN was able to take the draft, the pregame and highlight shows, and other NFL programming to a new level."

Jon Miller and Joe Morgan served as the longtime voices of the network's centerpiece Sunday Night Baseball broadcasts through the 2010 season. Steve Phillips joined the announcing team for the 2009 season, but was later dismissed by the network that October. In December 2010, ESPN announced that Orel Hersheiser, Dan Shulman and Bobby Valentine would be the new announcers of Sunday Night Baseball for the 2011 season. Valentine went back to managing after the 2011 season and was replaced by Terry Francona (Valentine and Francona essentially switched duties; Valentine became manager of the Boston Red Sox and
