Can Someone Please Explain TMZ To Me

Can someone please explain TMZ to me. Celebrity gossip??? Once again this critical thinker is confused in terms of why do we care? Why are major news networks such as Fox entertaining this crap as a part of their newscasts? The director/producer, spokesperson or whatever he calls himself of TMZ is in my opinion nauseating. Maybe someone who is a reader of this blog can help me out. I did say "In my opinion." As always I welcome yours.
