Squawk Box is an American business news television program that airs from 6 to 9 a.m. Eastern time on CNBC. The program is co-hosted by Joe Kernen, Becky Quick, and Andrew Ross Sorkin. Since debuting in 1995, the show has spawned a number of versions across CNBC's international channels, many of which employ a similar format. The program title originates from a term used in investment banks and stock brokerages for a permanent voice circuit or intercom used to communicate stock deals or sales priorities; it also may refer to the squawk of a bird, like a peacock, which is the logo of CNBC. Format Dubbed "our pre-game show" by regular co-host Joe Kernen, Squawk Box features early-morning analysis of and breaking news from the financial markets, along with considerable banter between the hosts and their guests – original host Mark Haines stressed the need to "inject a little fun" into business news in the early morning.

Regular contributors to the show include Sharon Epperson (NYMEX), Rick Santelli (Chicago), Steve Liesman, Guy Adami and CNBC senior analyst Ron Insana. Meteorologists from The Weather Channel contribute to the "Business Travel Forecast" segments.

Alexis Glick joined the team as senior trading correspondent in May 2003, while Bartiromo stepped down from her position in 2004 to concentrate on other duties. Becky Quick later replaced Glick as a reporter. For many years the program covered the opening bells of the New York Stock Exchange and NASDAQ Stock Market at 9:30 a.m. Eastern Time. Other regular segments included the Squawk Exchange, where the team (particularly Faber and Kernen) shared banter on various topics, On the Box (rapid-fire summaries of the day's headlines) and Joe's World, where Kernen sounded off on the day's notable stock stories. During the period when CNBC's online presence was housed at MSN Money, the show held its
