Brockman represents the worst of his profession; frequently judgmental, careerist to the point of absurdity, and more than willing to film and sensationalize a schmaltzy, emotion driven puff piece for the sake of a few extra ratings points. (As with most Simpsons characters, Brockman's ethics and competence vary according to the needs of the episode.) He has been seen throwing tantrums because he cannot find certain snack foods, and once blithely announced that the boom operator on his news program was being fired the next morning (for which he took a clout on the head from the angry soon-to-be-ex-employee). He seems to command excessive levels of power within Channel 6, even having a segment of the news programme to air his own (usually highly reactionary) opinions on current issues called My Two Cents. Despite all of this, he has won a string of media awards, but is most proud of his unspecified trophy from Del Monte. He was also a war correspondent during the Vietnam War, the Soviet war in Afghanistan, and the Gulf War (although, as he just says "Iraq", he could have been referring to the Iran–Iraq War). He also frequently uses botox, having a saggy face without it.
Brockman has a daughter, and has jealously mentioned his sister, who is a White House correspondent for CNN. Brockman owns a collie named Jessica, whom he had "fixed", and drives a blue Mercedes-Benz S420.
In "Dog of Death", Brockman won the multi-million-dollar ($130 million) state lottery jackpot and left the news desk while still on the air. But, he remained a news anchor because he was under contract, though he also admitted that he likes making $500,000-a-year. He also has an ongoing feud with traffic reporter Arnie Pie, and has been shown to criticize Pie's reporting and also even chuckle when it was thought Pie had died in a helicopter accident. He mentioned to Pie that he made some smart investments when Arnie complained about the size of Brockman's house.
He is also characterized by using news-speak in everyday language, for example, "This just in, go to hell!" In "Tennis the Menace", it was revealed that his "wit" is provided by a microphone, earpiece and a communications team in a nearby van. He has been seen, more than once, stretching his face and removing wrinkles by clipping a clothes-pin to the back of his head. In addition to his news career, Brockman writes a column for PC Magazine called "Making the Most of Your Modem". In "Homerazzi" Brockman is revealed to have a "thing" for bondage.
Brockman's most famous phrase, repeated in various guises on internet message boards and within popular culture is "And I, for one, welcome our new insect overlords". Another notable quote is "I've said it before and I'll say it again, democracy simply doesn't work".
Brockman's penchant for using offensive language works against him in the 400th episode, "You Kent Always Say What You Want", where, after Homer accidentally spills coffee on Brockman's crotch, he shouts, what Ned Flanders calls, a "super swear" that shocked everyone who watched it. Brockman was demoted to weather man due to the station paying a fine to the FCC, but was fired when the network executives deliberately mistook a ring of Splenda in Brockman's coffee for cocaine. Brockman was later given his job back to silence him (after doing an expose that was seen on YouTube uncovering the real reason the FCC is cracking down on obscenity in the media), with a 50% raise, making his new salary $750,000-a-year.
