Disney's ESPN is cutting about 300 jobs, or 4 percent of its staff, amid signs that the traditional cable bundle is less far-reaching than it once was.

ESPN spokeswoman Amy Phillips confirmed the number of job losses Wednesday.

The sports channel is one of the linchpins of the traditional cable bundle of hundreds of channels, which is under pressure from viewers migrating online. A few are choosing to bypass paying for a cable subscription entirely. Disney in August trimmed a profit outlook because more people were not subscribing to cable.

ESPN CEO John Skipper says, in a memo to employees that was posted online, these cuts are part of changes being made to keep ESPN as the "premier sports destination on any platform."
