46 did do a 7:00 newscast when it first became
a CBS affiliate, and you probably know how that
came out. As for 5, Fox stations have always done
extremely well with entertainment shows at that
time (perhaps one reason Fox doesn't do a network
newscast on its broadcast outlets).
But I've seen other stations switch the time of the
network broadcast from 7 to 6:30 and insert local
news at 7 (WUSA/9 Washington, DC, and WXYZ/7
Detroit come immediately to mind) and done just fine.
(You could get me on Washington: WRC/4 runs NBC
Nightly News at 7 and has for years, so there's an
analogy with Atlanta.) Moving Charlie Gibson to 6:30
in Atlanta is something I'd like to see, not that I expect
to.
BTW, Bill Hoffman is the first g.m. in Atlanta that I've
been enthusiastic about since Jeff Davidson at Channel
11 in the late '70s. Jeff implemented the "11 Alive" moniker
and worked overtime to make the market aware of Channel 11
(plus, he was the first g.m. to make that station profitable).
It wasn't enough to keep ABC, but you have to admit, 11 is
not the also-ran it was in the '50s, '60s, and early '70s.
Hoffman, as I said in a previous post, seems to be listening
to his audience. In his case, I indirectly quote one of his
predecessors, Fred Barber, the g.m. who switched Channel 2
to ABC: managers of number-one stations have a tendency to
not want to rock the boat. That, says Barber, is the fastest
way to lose your number-one ranking. I don't think Hoffman
is going to be one of those "if it ain't broke don't fix it" kind
of people.
