To watch ESPN, there are several options available depending on whether one wants to use cable or stream online. One can watch ESPN by:

• Streaming through live TV services such as Hulu + Live TV, Sling TV, fuboTV, DirecTV Stream, or YouTube TV. These services offer access to ESPN as part of their channel lineups and often come with free trials or promotional discounts for new users.
• Using the ESPN app or ESPN.com website by logging in with ESPN credentials or through a subscription package from an affiliated pay-TV provider.
• Subscribing to ESPN+, which is ESPN's dedicated streaming service providing live events and exclusive content for $11.99 per month, or through bundle packages with Hulu and Disney+.
• Watching on TV-connected devices like Amazon Fire TV, Apple TV, Roku, Chromecast, gaming consoles, and smart TVs through the ESPN app.

The streaming options provide flexibility for those who have cut the cable cord, with choices to watch via web browsers, mobile devices, or TV devices. There are often free trials available from services like Hulu + Live TV, fuboTV, Sling TV, and DirecTV Stream, making it possible to try watching ESPN without immediate payment.

In summary, the most common and convenient ways are to subscribe to a live TV streaming service with ESPN included or to use the ESPN app with a pay-TV login or ESPN+ subscription.
