Spiderman comic book question

i recently started reading comic books again, and starting getting the first civil war issues. I get the spiderman issue, and hes calling Iron Man boss. What the hell is going on?

I havent read any comics in a while so i must have missed some important stuff. Can someone please tell me why Spidey is calling Iron man boss?

i tried to get into Comics once, but then i found out how huge the Marvel and DC universe is and i got confused.. and yeh its freaking huge. GarchomPro

yeah, thats why they brought out the "ultimate" stuff. They started it from scratch, which i didnt really like, since i started reading the comics when i was a kind and i didnt really want to go through it all again with a slightly different slant put on it.
