Would you be willing to share more? That seems like a very ripe (can't think of a better word) place to be working in.

F1TV and YouTube Live (esports).

YouTube for recap highlight.

Some random sites for soccer.

I mostly discuss with my partner.

Curious why attending in person or otherwise watching the game is not among the considerations.

I have a very cheap TV package that includes something like a dozen, maybe two dozen sports channels. That's where I mostly watch soccer, but very rarely these days. I watch no other sport, and I pay for all of those channels because they come together in a bundle

I occasionally go on r/soccer purely for goal highlights

I used to use sofascore to keep track of games, but I don't anymore since I rarely sit down to watch matches. When I do want to find out when a particular match is, I will search on google

I do play premier league fantasy with a few buddies. We have our own league

Also, I don't think hn is the place to do research about people and their sports-watching habits, since most people here won't watch any sports regularly. A better place would be to go to some communities related to a certain sport and interact with the people there to find out how they do things; but also, if you're not into sports yourself and know a particular sport in and out and the culture associated with it, it's probably not the best idea to do a startup about this

I used to (mid-2000s to 2020, basically) live on message boards and listen to sports radio every day; I basically lived and breathed college football. Nowadays it's pretty much just a curated list of sports writers I like on a sports-only twitter account followed by watching most of my teams' games + a handful of interesting games going on that day using YouTube TV. There's something about the pervasive, constant nature of content these days that seems to have taken a lot of the fun out of it for me.
