Many in Congress would no doubt like to stick it to FCC chief Tom Wheeler for some of his bold moves. Now they have a chance. Four senators have introduced a bill that would grandfather existing JSAs. Passage would give a nice boost to broadcasters who do nothing but provide a superior news and entertainment TV service to the American public free of charge. And it would show that Congress still has some say in FCC affairs. Addendum: The NAB is going to ask the FCC to give broadcasters more time to move their channels during the incentive auction repack. The FCC should grant it because it just can’t be done in 39 months.
