This is from the Wikipedia page for YES--
"In March 2023, YES launched a direct-to-consumer streaming service that included access to a 24/7 feed of YES Network and all New York Yankees, Brooklyn Nets and New York Liberty games appearing on YES. The service is only available in areas where YES is also featured on local cable. The service costs $24.99 per month or $239.99 a year, but was initially offered for an introductory price of $19.99 a month or $199.99 a year.[26]"
That seems pricey to me, but it includes two other sports. I wonder how much they make on advertising.
