If you’re located in Europe there’s a good chance that you’ll be able to receive many German television channels for free via satellite. If you don‘t have a satellite dish, it may require a one-time 100+ € investment.
The biggest selection is available on SES Astra, 19.2° East.
Many cable providers also offer foreign language packets, but that depends a lot on your location (and probably becomes more costly quickly).
You should at least receive broadcasts from Deutsche Welle TV, the German state-funded foreign TV service, partially in English or local languages.
A lot of movies released on discs (DVD/BD) that are intended for sale in “Region 2” (i.e. Europe) will feature audio tracks for multiple languages, often including German. If you don’t have any, your friends, local library or next flea-market may and the usual online shops definitely do.
Most public and ad-funded TV stations have video on demand services for their (original) programming, at least for the last week or so, but to access them you usually need to be “in Germany”. That means either the IP address that your service provider assigned to your account or the one of a proxy you’re using needs to be considered German (or Austrian or Swiss). The established term for these VOD portals is Mediathek in German.
