20/20 is a popular television series that focuses on non-fiction topics ranging from human interest to politics. The series began in 1976 and has been running ever since. Its popularity is evidenced by its astounding ratings. Its ratings are down a little over the past two years, but are still over five million.
The show has had a total of eight presenters. Perhaps the most well known of these eight presenters was Barbara Walters. She was the presenter of 20/20 when the show covered an interview of the President of the United States Bill Clinton's former mistress Monica Lewinsky. That episode had ratings of 70 million. Following Barbara Walters was the also immensely popular Diane Sawyer, who was the show's anchor from 1998-2000. Correspondents have included names like Carl Sagan and Geraldo Rivera.
20/20 focuses on investigative journalism. They cover some of the most pressing topics in the world. However, they have also branched out into entertainment topics and popular culture topics, as have most news series. 20/20 also picks up obscure topics and brings them to the forefront of news. Examples include underreported medical conditions and unknown living conditions in various parts of the world -- including the United States.
Most 20/20 episodes include in-depth news stories. However, 20/20 also does even more in-depth special one and two-hour episodes. These traverse a wide range of topics from transgenderism to crime stories. The series is still currently running and is headed by Elizabeth Vargas and Chris Cuomo. This year (2012) marks the show's 34th season.
