i used to push for on air credit...now i don't really care, for the most part. in my short 3 1/2 year career, there have been 2 times where i honestly think i should have where i didn't.
1) shot an entire pkg by myself, including interviews, came back, wrote it for the weather guy....he voiced it, i cut it, and he got the congrats when it turned out great, but he was humble enough to refer everyone who patted him on the back to me (which i did appreciate a lot)
2) late breaking news on a sunday night...no morning show, but whatever. small town fire about 45 minutes away, but it's downtown, they've called 3 other fire departments, and they're running out of water. get up there, shoot for half hour or so, the fire's out, get some interviews, came back, cut a natsot from it, wrote up a script for the natsot...only to have a reporter front it for our midday show, with my script, minus my name.
other than that, i've pretty much given up.
