But you get a discount on electric installation if you sign up for your new service online.
Internet service isn't just entertainment: It is communication, banking, and lots of very basic things folks need in life. It just happens to be multi-purpose, so you get the entertainment value as well.
Many jobs require internet access to apply: Fewer and fewer take any sort of paper applications and not everywhere has kiosks to apply and test at (low paying jobs, at least). Heck, game disks are getting rarer, so you sometimes need to be online to use a PC game. Lots of research for school papers is done online.
Also, communication. Few folks send snail mail letters anymore due to email. Chat programs work well too.
If you aren't connected to the internet, you are at a disadvantage. I cannot say that about television in general or a football match - going without those sometimes means you don't have as much to talk about with folks that consume those.
