I don't know where you're based but I would offer the BBC
TV - take your pick of classic shows. Radio - 6 music for me. Education - provides resources for all school key stages in line with the UK curriculum. Sports - a bit sporadic but you can get everything except baseball at some point in the year. Arts - broadcasts the Glastonbury festival. Live shows you can attend and be in the audience.
All for £170 a year and no ads.
