You might need to recall just how crazy it was e.g. literal shrines to boy bands were just normal. To cover every inch of your bedroom walls and ceiling with photos of a celebrity crush was not unheard of. At school, every conversation could be about these obsessions. Folders/files would be covered with pledges of devotion.

No comment on how it is today, but looking back it was terrifyingly nuts - full on religious fervour to the point of mental disorder. When bands broke or people married/died, there would be full on breakdowns and sympathy suicides.

The lack of information might have helped exacerbate the religious mystery and make more space for imagination, fantasy and faith.
