There's been a lot of change over at 94.1 WIP the past few months. The station is launching not one, but two new shows.

Now, get ready for a third.

Former 97.5 The Fanatic host Jon Marks will take over the station's 6 to 10 p.m. timeslot, replacing current host Brian Haddad, according to sources with knowledge of the situation. Marks' first show will air Tuesday, February 7.

Marks surprised many when he decided to leave his job co-hosting The Fanatic's Mornings with Anthony Gargano after his contract expired on October 20. Before that, Marks worked with Mike Missanelli, and helped the popular afternoon host defeat his competition, WIP's Howard Eskin in the ratings. He also co-hosted The Jon and Sean Show with former Fanatic personality Sean Brace.

Haddad has been with the station since January of 2012. He'll continue his role as the station's creative services director, writing and producing a lot of the segments listeners hear throughout the day.

The move comes on the heels of several line-up changes by WIP's program director Spike Eskin after combative afternoon host Josh Innes was fired.

Back in October, WIP hired former SportsNet New York host Chris Carlin and paired him with former Eagles linebacker Ike Reese to fill the station's 2 to 6 p.m. drive-time slot. Popular Comcast SportsNet host Michael Barkann was also forced out and replaced with former Fanatic host Joe DeCamara and ex-Eagles fullback Jon Ritchie, who currently anchor the stations 10 a.m. to 2 p.m. afternoon slot.

Now the only slot the station needs to worry about is the morning shift, which longtime host Angelo Cataldi has said he's considering vacating when his contract expires at the end of the year.
