For some reason, media companies often don't get that the presenters of a show are usually absolutely core to the brand and are a much more valuable asset than the sets, the name or the logo.
I didn't like Top Gear because of the logo or the name "Top Gear" or even because it was a car show - I'm not really a car enthusiast. I tuned in every week because of the incredible chemistry and humour of the presenters. Remove them, as the BBC did, and 95% of the appeal was gone. Replacing Clarkson with some guy from Friends who sounds like he's reading his lines at gunpoint (that unlike the previous hosts he didn't write himself) had no interest from me, and indeed most people. Top Gear died overnight, and is in zombie mode like the Simpsons now, they keep changing the hosts hoping to recreate the magic but the ratings don't budge, it's dead.
Top Gear, GiantBomb, =3, all sorts of late-night talkshows, and, of course, G4. All ruined by changing the presenters, victims of clueless media dunces who don't seem to understand how their own industry works. Adam Sessler is the poster boy for this arrogant and clueless corporate stupidity.
