! Series Hosts

The ! Series is hosted by Ashley Neleh, who uses different hosting personalities for different shows in the series.

Hosts
Hosting personalities correspond directly to the actual network editions of the show, with the exception of Ivanka Trump taking over her father's role in The Apprent!ce starting from the show's third season and celebrity edition, and American Idol's Ryan Seacrest as the red carpet anchor for all season finale events. The Showdown! series also includes a wide variety of other hosts such as Big Brother UK's Davina McCall.

Jeff Probst - The Surv!vor series

Phil Keoghan - The Amaz!ng Race series

Donald Trump - The Apprent!ce 1 & 2

Ivanka Trump - The Apprent!ce 3: Celebrity Apprent!ce

Julie Chen - The B!g Brother series

Ryan Seacrest - Red carpet anchor

Guest Hosts
There have not been many permanent season-long guest hosts within the series. Surv!vor: Tocantins was the first and only season to feature 3 hosts instead of the usual 1. The Apprent!ce features panelists who help the host in deciding the outcome of the Board Room meetings and firings, while task judges help to decide the winning team of the episode's task. In Surv!vor, challenge facilitators and temporary hosts are more common in the series compared to permanent guest hosts. Facilitators are in charge of taking over the publishing of challenges and Tr!bal Councils for temporary periods, which have already been constructed in advance by the host.
