- first of all, some satellite and DVB-C/T boxes and also TVs such as my ages old Samsung can update their firmware over the air (e.g. [1], page 54). It's possible to use a similar channel to distribute advertising as well.
- embedded WiFi that auto-connects to open networks such as many ISP routers provision in exchange for allowing the line owner access to the provider's hotspot network
- embed a LTE modem
The first way costs money, as renting aerial transmission time is not cheap, LTE modems + data plans are cheaper but still have a hardware cost attached even if manufacturers cut deals with providers, and almost every TV these days has a wifi stack built in.
