That might be because of how much more diversified media coverage is now. For the most part, many great creators (and to be honest, celebrities and influencers too) are famous in a certain field, not across the entire world. The greatest philosophers of this era are likely only well known among other philosophers, and academics in related fields. Same with mathematicians, scientists, historians, etc. Meanwhile many great artists are only known among others in their field. Could the 'mainstream' media cover every genius or great creator? Probably not, there wouldn't be enough room. There are so many great people creating works and making discoveries that you likely won't ever know about more than 1% of them, at most.
