Well - they haven't been #1 since they had Bob and Mark, they hadn't been #1 for a long time since then. With 20 some odd signals on the air in Anchorage, I doubt a classic rock could be #1 without a real strong morning product. W&W are decent, the only reason they don't 'kick ass' in this town is because Bob and Mark have been here for years and have been #1 for most of that time, I don't think Anchorage rock listeners for the most part are even giving them a chance, just like they didn't give Glenner and Jerry a chance (see their 8 month run in Anchorage for more details). They're the home team, and they do a fine job, it'll be sad when those two hang it up for good.
Also, the market for classic rock has changed, you have Bob which dabbles in a bit of everything, X-Rock which is probaly 70/30 classic rock to new rock, KOOL which has transitioned to classic hits within the last 2 years, Fox, and of course KWHL, who's flirted with the classics forever it seems. The market is too fragmented for stations that play Sweet Home Alabama! Not to say that KBFX couldn't be successful again, but I think it might be time to do something different. That's a toughy, as you have 3 other rock stations on the air, would you WANT to do something rock-based again?
Maybe Clear Channel will bring their canned La Preciosa Spanish format up...haha. OK, they won't do that, but it'll be interesting to see what happens.
