The Club Jenna purchase was a disaster and their inhouse web ventures have done just as bad. The company that did their web marketing fucked them big time by giving pretty much all of their archived pay webcontent (cyberclub) for free. Christie was too late to the party as far as getting into the hardcore part of the industry.
The bunny itself is the most marketable part of the brand now. However even that has lost much of its luster due to the fact that they put the damn logo on anything and everything you could possibly imagine.
As far as the magazine goes, MAXIM/STUFF/FHM cut into their sales. Even with STUFF/FHM gone, they never recovered. Seven years ago they brought in a former MAXIM editor to head the magazine, it was a disaster. A lot of their loyal readers jumped ship within the last 10 years because of the shitty Z list celeb pictorials. A lot of them also started to bail when Hef started putting is lookalike girlfriends or girls that looked like them in the magazine on regular basis. A lot of the feedback was negative, and they did try and change it, but the damage had been done.
That being said, they got it right with who they just picked for Playmate of the Year.
