you could never trust the BBC. You just didn't have access to anything questioning it, so there was no challenge, which made it uncontested and therefore "taught" you to trust it. The mass media manufactured consent for the Vietnam war. It lied about Gulf of Tonkin. It lied about all the other wars, as well. It panicked you into crime scares, drug scares, youth scares.

There are great book from the 1980s about the moral panics the media created out of thin air, before the CNN disrupt. It made you believe that "rockers" were attacking UK institutions (Stanley Cohen, Mods and Rockers). It made people believe satanist cults were abducting their children. It made moms believe Dungeons and Dragons, the GAM, was a gateway to that, and thus created "MADD", Moms Against Dungeons and Dragons.

All of these panics still exist today. All the war lies still exist. But we live in a plural communication structure, and there's always someone that tells you this is BS. It's easier now to not trust them, as there are circles of distrust, and they are no longer just local.

Also, wikipedia has been captured long ago.
