It's on a par with interviewees who start their answers to questions with 'so'.
Interviewer: What are your plans for the weekend?
Interviewee: So, I'm going to get up late and slob around.
Listen out for it, you'll hear it cropping up all over the place.
As for 'absolutely', you would think that a simple 'yes' would do just as well, but apparently not. These silly, irritating media-person speaking habits come to light because we all hear them, but they're just as prevalent in the commercial world, I assure you.
I have a client who seems to have infected all his fellow Directors with the habit of 'going forward' all the time. Everything is discussed in terms of going forward, instead of 'from now on', or 'in future'. Going forward we'll be buying a new file-server, etc.
I could go on, but you would be absolutely bored, going forward.
