UPN will close the all-important February sweeps period by looking back at "America's Next Top Model" past and then premiering the latest installment of the popular franchise. In addition, as UPN looks into its future, the netlet has taken steps to ensure that "Model" will be part of its family for at least another year.

On Tuesday, March 1, UPN will air a one-hour special focusing on the girls from the recently completed third season of "Top Model," showing how their lives have changed since Tyra Banks and company introduced them to fancy walking, Japanese street style and fame. The very next night, the fourth cycle of "Top Model" will premiere in its standard Wednesday 8 p.m. ET time period. UPN will use the "Top Model" premiere as a lead-in for the finale of "The Road to Stardom with Missy Elliott."

After breaking out in its second installment with an average of 6.3 million viewers per week last spring, the third season of "Top Model" came down to earth a bit, averaging just over 5 million per episode. While the total viewers were down, "Top Model" helped anchor the tough Wednesday night for UPN, providing strong demographic ratings and serving as a strong launching pad for the highly regarded freshman drama "Kevin Hill."

In addition to laying the groundwork for the show's fourth cycle, UPN announced on Wednesday (Jan. 19) that "Top Model" will return next season with its fifth and sixth peek into the world of high fashion modeling and cat-fighting.

Tyra Banks and the rest of the on-air and behind-the-scenes talent are expected to return.
