Where newspapers will cater to lifestyles and interests by either lumping them in with diverse others so that you can skip to that article on computer simulation , or suprise you by including a feature virtual reality when it's not the sort of thing they're known to run; magazines give it to you on a plate.

Newsletters are happy to indulge their readers' proclivities and may do so at the individual business level. Trade journals naturally deal with lifestyle interests through the industries that support them and academic journals take an interest in their studies.
