The World's Strongest Man (2015-2016)

20/20 continues to combine hard-hitting investigative reports, newsmaker interviews and compelling human interest and feature stories.

Sister Wives explores the complex daily life of a polygamist family. Sister Wives introduces audiences to husband Kody -- along with his three wives; Meri, Janelle and Christine and their combined 13 children -- showing how they attempt to navigate life as a "normal" family in a society that shuns their lifestyle. From their unconventional family structure and living arrangements to financial challenges, each half hour episode exposes the inner workings of a polygamist household, revealing the unexpectedly tight-knit and loving relationships between Kody's wives.

Jimmy Kimmel Live features a diverse lineup of guests that include celebrities, athletes, musical acts, comedians and human-interest subjects, along with comedy bits and a house band.

The First 48 follows detectives from around the country during these first critical hours as they race against time to find the suspect. Gritty and fast-paced, it takes viewers behind the scenes of real-life investigations with unprecedented access to crime scenes, autopsies, forensic processing, and interrogations.

Surviving Earth will take an incredible journey into prehistory to learn the lessons from past mass extinctions.

Adopting cutting-edge digital technology, each episode transports the viewer back to meet the bizarre and amazing creatures and breathtaking landscapes of a vibrant lost world. Audiences will witness how life finds a way to survive on a planet where meteors fall, super volcanoes erupt, seas boil and the land moves. From the creators of "Walking with Dinosaurs" and "Primeval," these are the stories of the survivors, fighters and lucky ones that shaped the world we live in.
