WTMJ-AM (620) has nearly four months to come up with a new afternoon show to replace the retiring Jonathan Green and his "Green House."

The transition comes as Milwaukee radio begins its switch from the old ratings system to Arbitron's new personal people meters. And, frankly, it's likely that 'TMJ management will watch and see how the first few months of the new ratings shake out before deciding on what's coming next.

My guess is that you won't see an extension of the Charlie Sykes-Jeff Wagner bloc of conservative talk. Such a move would be a direct assault on powerhouse Mark Belling over on WISN-AM (1130).

For years now, WTMJ has operated three distinct formats in its broadcast day.

Weekdays open with a news/information program now hosted by Gene Mueller and John Jagler, moving into the middle of the day's political talk. There's an odd hour of syndicated programming -- consumer adviser Clark Howard -- then back to mostly news/information with the Greenhouse. The station focuses on sports programming starting at 6 p.m. and features plenty of sports game coverage (Dennis Miller's show is there as a filler).

The future of that blended format, obviously, depends on the Arbitron numbers. If you look south of the state line, evening sports programming didn't survive on WGN-AM (720), which holds a spot in the Chicago market similar to WTMJ's position here.

So let's assume that a post-Green "Greenhouse" fills the 3 to 6 p.m. slot come 2011. Who would host?

Here are some possibilities to ponder:

• One easy guess is former WTMJer Mark Reardon, who now does talk from 2 to 4 p.m. weekdays on St. Louis' KMOX-AM, and hosts two more hours of news from 4 to 6 p.m. He's a possibility, already known to listeners as a fill-in on the show and he knows the market well. But would he leave a bigger market?
• How about Steve Cochran? The fired WGN host did afternoon drive time by balancing his standup comic persona with all the business that has to be done during afternoon drive. But there's no evidence Cochran knows much about Milwaukee, and there's no immediate connection between him and listeners here.
• What about Mueller or Jagler? Given the cost-cutting that's gone on at WTMJ, what about moving one morning show host to afternoons and having both drive times with a single headliner? It's a possibility that helps the bottom line.
• Then there's Phil Cianciola. The former second "Green House" second banana knows the show. And without Green, the tensions that led to his firing would be gone. But there's no evidence that WTMJ has any interest at all in him. And, as he said on his podcast Monday, Cianciola is concentrating on that project, which will mark its first anniversary in October.

"They apparently didn't value me enough to keep me around then, what is different now?" Cianciola said of WTMJ management on the podcast hosted by OnMilwaukee.com. He noted that he never was able to learn what the station's plans were for a post-Green afternoon show.

"After working 14 years, you could understand that would be troubling. It seems I should have been part of that plan."

As for Cianciola's plan, "I moved on the minute I started planning the Philcast last fall, to be serious. I'm going full speed ahead with this. This is my deal.

"It's probably the thing I'm proudest of that I've accomplished in my entire career, because I did it all myself, and it's going quite well."

His goal, of course, is to make a living at the daily podcast.

"For me, right now, it's heads down, work hard as I've always done and do what I do best."
