I watch it on an ESPN+ subscription. I think it's around $9.95/month now (was $7.95 when I originally signed up). You get about 7 or 8 Championship games in a week, plus a few League One and League Two, FA Cup and Carabao Cup games. Not to mention a lot of the International games.
There's also Spanish, German, Dutch and Belgian football, and a whole range of other sports from Cricket and Golf to Tennis and Swimming.
And if you miss a game, they are usually available on-demand for a week or so.
The Scottish Championship Friday night games used to be streamed on there too, but they aren't available this season. There are still a few cup games from Scotland shown from time to time.
Most Smart TVs have the ESPN app available, but you can also watch on your computer or phone.
I sound like I'm an ESPN+ shill, but it's easily the best value subscription I have.
