At least a Kagi search (for FAST Service Acronym) gives me:
"FAST (free ad-supported streaming TV) is a business model. It is, as the name implies, a streaming TV service that supplies programming for free. Period. Almost all of the FAST services offer linear channels and on demand options."
Give Tubi a try, it's like broadcast TV and the lower tier of cable channels died and went to heaven. Fox news is spending heavily on it at a loss right now so it's in the early phase of the enshittification cycle. (I didn't take it personally when I gave it my email and it showed me retargeted ads for brands I'd disengaged with years ago)
