Sure, you should do it. I'm not sure why you're even asking the question.
Upside: More publicity and exposure, a chance to attract new fans.
Downside: Maybe they'll make some mistakes, take some quotes out of context, and/or portray you in an unflattering light somehow. But I doubt they'd deliberately try and defame you. If there are mistakes or omissions, they're likely to be innocent ones out of ignorance and time constraints, not malice. Look at how they portray other people they interview on similar segments.
The journalists I've had the experience of dealing with are not very technically minded, and they're always constrained by time. So don't expect them to do as thorough a job as you'd like. But if that's OK, it seems to be an opportunity for more publicity and an opportunity to attract new viewers.
