This the web timeline of how the perception of content has evolved as per its role on the web:
1997: content is king
2000: content supports design constraints (and content strategy for the web becomes an official approach)
2004: content supports social media constraints
2008: content supports browser constraints
2012: content supports user experience constraints (and helps find meaning in content)
2016: content supports responsive web design constraints (there’s a book, of course, content strategy for mobile)
2020: content supports content strategy constraints
2022: content IS KING AGAIN !
