Before I ask my question, allow me to assemble some facts and provide some background:
If you'll recall (and I'm sure many of you do), several years back (sometime in 2002, I believe), Fremantle Media announced a new policy: Rod Roddy, The Price is Right's long-time announcer and an icon within the show's lore, could no longer be seen on-camera. Supposedly, this was because on no other Fremantle show was the announcer seen on television, and they wanted to keep The Price is Right uniform with that rule.
Rumors ran rampant on the game show boards that the driving force behind this sudden edict was the silver-haired Plinkomaster himself, Bob Barker. Depending on who you talked to, it either stemmed from Barker's desire to be the sole personality associated with the show (also a reason given to explain the departure of Janice and co. in 2000) or from some sort of falling out or disagreement between Bob and Rod.
At the same time, Rod was growing frailer because of his illness. In his last television appearance (on the premiere of the 32nd season), he looked gaunt and sickly. To me, this signifies that perhaps Fremantle didn't want Rod on television because of the way he looked; or maybe Rod himself didn't want people to see him in his frail state, instead preferring for the legions of Price fans to remember him in his ebullient, garishly-clothed heyday.
Of course, Rod died, Rich Fields took his place, and suddenly Fremantle reversed their uniform announcer policy. If I recall correctly (and correct me if I'm not), Rich actually made onscreen appearances, BUT they were nowhere near as consistent or frequent as Johnny Olsen's or Rod's. So on the one hand, the fact that he made appearances at all would seem to suggest that maybe Bob's ego wasn't at play, and it was just a concern over Rod's appearance; on the other hand, the fact that they were infrequent seems to point to the Bob's ego theory. Worthy of note is the fact that Rich's appearances have SKYROCKETED since Drew Carey took over in 2007.
Now, this brings me to my question: does anyone know what the real reason was, or have any information from which we can draw conclusions and/or analyze? To recap, my four theories are (in no particular order):
1.) Bob's ego at play
2.) A falling out between Bob and Rod
3.) Rod looking sickly and not wanting to be shown
4.) Fremantle not wanting sickly Rod to be shown
