From the 5 a.m. wake up calls and 16-hour work days to a deadly diet of junk food, life on the campaign trail presented unique challenges to FOX News' embed producers who crisscrossed the country providing instant updates on the candidates' every move.

Their presence changed the dynamic of election coverage -- as they made every scripted and unscripted moment available for all to see. Tune in to "Assignment: Campaign Trail" at 2 p.m. and 11 p.m. EST Sunday to get a behind-the-scenes look at FOX News' coverage of the 2-year presidential cycle, featuring embed producers Bonney Kapp, Cristina Corbin, Mosheh Oinounou and Shushannah Walshe.

The presidential campaign of 2008 has been called historic for many reasons: the first African-American president was elected, a female candidate survived longer in the primary season than ever before and the Republican party selected a woman for its vice presidential nominee.

FOX News Channel spent more money, sent more people out to follow the candidates and developed new technology to cover the campaigns. The appetite for 24-hour cable news nearly doubled in prime-time and it was the most-watched political saga the country has ever seen.

"Assignment: Campaign Trail" is told -- FOX-style -- by the dedicated FNC correspondents and crews who fed viewers around-the-clock coverage from the most grueling campaign in history.
