Normally (at least in the now-distant pre-internet past), newspapers were supposed to be as unbiased as reasonably possible and just report the news, though they frequently had opinion sections ("op-ed") which were clearly marked as such. Magazines catered to specific groups of people with specific interests, so those could be more biased (e.g., Motor Trend was quite blatant about its pro-car bias, for obvious reasons). But yes, along with this was consistency in ideology: you wouldn't buy Motor Trend and expect to see both pro- and anti-car opinions expressed there, and if you didn't like cars and car culture, you wouldn't buy the magazine to begin with.
