It may, but only if he has been involved in the reporting or investigation of the case that he is being called to jury duty for.
Lawyers and judges alike do not want anyone to serve on a jury if they have any strong preconceived opinions about the case. These strong opinions may come from what they have heard from others or seen in the media. Ideally, they would like people who have never heard of the case that is being argued in court.
Another issue is if he has any special knowledge about the case, or it's evidence, beyond what will be discussed and argued about in court. Judges and lawyers want to decide everything each juror knows about a case. They do not like a juror who has extensive knowledge about a case beyond what is brought up in the court proceedings. If your husband knows certain information about the case that he was privy to because of his position in the news media, then this may disqualify him as well.
He will still need to go to court on the first day of jury service, but make sure he discusses his roll in the media or any experience he has with the case.
If he does not know any information about the case being argued, then he will likely not be disqualified for just the fact that he works in the news media.
