American Express cardholders will get 30 days of free service from ESPN+, ESPN’s new streaming video service, when it launches this Thursday, after the credit card company announced it would be the official launch sponsor.

Cardholders will have to enroll in the service during launch week to qualify for the 30-day trial, which can be canceled with no obligation. Those without Amex cards will likely get a 7-day free trial before the monthly $4.99 fee begins.

“It is fitting to have a renowned brand like American Express on board as the official launch sponsor for a renowned moment in our company’s history,” Ed Erhardt, president of ESPN global sales and marketing said in a statement. “Disney and ESPN continue to lead the industry in delivering innovative ad experiences and solutions for advertisers, and with ESPN+, we now have more opportunities to reach fans in new and engaging ways.”

Some sports fans are skeptical about the merits of ESPN+, which is designed to protect ESPN’s cable television partners. The Ringer reports a deeper look at the lineup reveals ESPN+ is likely to be underwhelming. Although the service may prove valuable to less-followed soccer, boxing, golf, tennis, rugby and cricket sports fans, devoted baseball and hockey fans are likely to be frustrated by slim offerings.

“It’s lacking the main thing sports fans want to watch: sports.”

“[It’s] programming not valuable enough to appear on one of ESPN’s eight cable networks (ESPN, ESPN2, ESPNU, ESPN Classic, ESPNews, ESPN Deportes, Longhorn Network, SEC Network),” opines The Ringer. “ESPN’s press release makes no mention of the NFL or NBA at all. There will be no Monday Night Football, and neither of ESPN’s two weekly NBA games will appear on the platform. Plus, no live event that is on one of ESPN’s eight cable networks will be on ESPN+.”

ESPN+ will be available on a redesigned ESPN app and through ESPN.com.
