Here's the problem with newsgroups :
1) It was not designed to distribute binary files - it was for text in a time before HTTP and forums.
2) To work around this limitation all binary data is encoded to 7bit text streams which results in a bloat factor 1.3333333 so if you have a 1GB file that becomes 1.333333GB of traffic you are pulling (overhead).
3) Because newsgroups was made for text a message (or post) would typically be limited to a length of 64kb~384kb so your 1.333333GB bloat file sits in millions of posts on the server (more overhead).
4) Because some posts might not get propagated properly and newsgroups are generally unreliable you need PARs which can add a further 20% bloat (much more overhead).
5) All this bloated traffic goes to one destination (the news server) and this is a big source of congestion on the network (all that overhead!).
6) It is very easy to see what users are downloading from the news group (much easier than on P2P).
So there you have the 6 main problems with news servers. There are many more but it all boils down to the fact that its a really old system that is used beyond its design limitations.
P2P is much more elegant and actually costs the ISPs less!! It uses less traffic (less overhead) and being local does not matter because the ISPs save more on infrastructure.
They do not have to invest in massive storage and throughput for their news server.
