There is a big difference in how news is marketed today compared with the old days.
Back in the day, news stories were chosen by Networks. Because there were a small number of Networks, the range of news stories was narrow. The financial incentive was to please advertisers by keeping viewership high. Viewer allegiances were “sticky”. It’s 6:00pm? That was Walter Cronkite time in my house. Unlikely anyone would change the channel. I mean, you had to stand up and walk to the TV to do that.
Nowadays, the majority of citizens get their daily news from social media. They do not usually choose the news provider… it is chosen by the social media platform. Most people have no idea the source of the news article they clicked on. The social media's incentive is to provide click bait which entice viewers to click through to the next page with a new set of ads, hence a new flow of revenue from each advertiser. The social media platform uses information they have on your preferences to guess what story will most likely get your “click”. They present customized versions of each chunk of “bait”, changing the newscaster’s gender, race and age to comply what they know about you. And they choose stories they know would interest you based on your search history and those of your friends. The choice was made in milliseconds. The guy sitting next to you in Starbucks likely was offered a different chunk of clickbait by the same social media platform.
This strategy results in “echo chambers” where people’s beliefs, and those of their social group, are reinforced. The fact you are seeing news stories about SLS may have something to do with “targeted market profiling” which was not available in the Apollo era. Of the following world circulation newspapers: Aljazeera, The Guardian, The Times of Israel, New York Times, Wall Street Journal, none had a story on SLS as a “front page” story in today’s US News section. However, if I ask Google for news, the top story offered is SLS. Google knows who I am and what my interests are.
So, to answer your question “… is Artemis attracting more media coverage today than early Apollo…?” I would question the assumption behind your question. There is a much larger volume of news stories, but they are much more narrowly targeted. What one person sees is more a function of that person’s marketable attributes than total news volume.
