I understand the necessity of local TV stations allowing storm warnings (especially tornado or floods) to take over the "dot one" channel. However, why don't these same channels give viewers "the national feed" on the "dot two" (or whatever) subchannel (and even promoting that "NBC coverage continues on 8.2" on a scroll)? Getting pretty tired of 3 channels devoted to a possible tornado 3 counties away, while they could easily put the network feed on a subchannel (or can they legally not do that)? Our FOX channel did a split screen with the World Cup, but of course audio was of the storm warning.
