As long as the venerable 20/20 newsmagazine brings in decent ratings it seems fairly certain that ABC won’t cancel it. Chris Cuomo and Elizabeth Vargas continue to co-host the TV series. The 35th season of 20/20 typically airs Friday nights at 10pm on the ABC network.

These are the TV show’s ratings for the 2011-12 season, the best way to tell if 20/20 will be cancelled or renewed for a 36th season (will it ever go away?).

These figures will be updated as the weeks progress so be sure to bookmark and return to this page:

Note: These ratings are collected by the Nielsen company and are the final national numbers.

The final nationals are typically released within 24 hours of the programming or, in the case of weekends and holidays, a couple days later.
