Bloomberg Disney investors have been concerned about ESPN for two years.Once again, its time to talk about ESPN. Since August 2015, when The Walt Disney Co. DIS, +0.13% initially began bringing down forecasts for its cable channels amid fears of cord-cutting, ESPN has been a dimming example of the trend and a big part of earnings discussions. Investors have continued to focus on the premium sports network as subscribers have declined and ESPN has laid off prominent workers amid plans for an independent streaming service. ESPN will be a focus again when Disney reports earnings Tuesday afternoon for its fiscal third quarter, which is a traditionally weak period for the media industry due to seasonal impacts. Heading into the quarterly earnings season, analysts anticipated the pay-TV industry would report the loss of more than 1 million subscribers.via
