I looked all this up on the internet and saw that this regulation was inacted in 2000!! Here is what I found:
The new rules apply both to C-Band (large dish) and DBS (small dish) satellite service providers. Under these rules, six superstations carried pursuant to a statutory copyright license are subject to program deletions to protect the contract rights of local television stations. The six superstations are KTLA-TV (Los Angeles), KWGN-TV (Denver), WGN-TV (Chicago), WPIX- TV (New York), WWOR-TV (New York), and WSBK-TV (Boston).
So, a question! How can Dish still have these stations as well as our local networks, yet DTV does not have them?
