hmm... just for the heck of it, how about vicki vale? she's a reporter (not sure if she's in tv, but i think she might be) who tends to work in the gotham area, but has been known to be elsewhere from time to time.
there's also leslie willis, who at some point will be come the villain livewire, but who started out in media. in the cartoon, she was a DJ, but in the comics, livewire was a TV reporter.
other than that, you can use real names. connie chung comes to mind. lori jordan, iirc, is a reporter for one of the networks. roz abrams. jane pauley.
take any of those or make up your own. whatever works.
