An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are at least temporarily archived. Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes visible.

Forums have a specific set of jargon associated with them; e.g. a single conversation is called a "thread".

A discussion forum is hierarchical or tree-like in structure: a forum can contain a number of subforums, each of which may have several topics. Within a forum's topic, each new discussion started is called a thread, and can be replied to by as many people as so wish.

Depending on the forum's settings, users can be anonymous or have to register with the forum and then subsequently log in in order to post messages. On most forums, users do not have to log in to read existing messages.

The modern forum originated from bulletin boards, and are a technological evolution of the dialup bulletin board system. From a technological standpoint, forums or boards are web applications managing user-generated content.

Gregg "Opie" Hughes (born May 23, 1963) and Anthony Cumia (born April 26, 1961) are the hosts of The Opie & Anthony Show, a talk radio program airing in the United States and Canada on XM Satellite Radio and Sirius Satellite Radio. Since the merger of the two satellite companies, this is now called Sirius/XM. It is co-hosted by stand up comedian Jim Norton. Based in New York City, the show was previously on WXRK-FM and WNEW-FM in New York, and prior to that, on WAAF-FM in Boston, Massachusetts.

On April 26, 2006, Opie and Anthony returned to the terrestrial airwaves after a four year absence, replacing CBS Radio's short-lived David Lee Roth Show, which aired mainly on the eastern coast of the United States. The terrestrial portion of the show ran until March 9, 2009. The team was terminated by WXRK-FM when it flipped formats from rock to Top 40.

The Opie & Anthony Show airs weekdays live from 6am through 10am ET exclusively on XM Radio Channel 105 and Sirius Radio Channel 206 "The Opie & Anthony Channel". Replays are available throughout the day on their XM and Sirius channels and on audible.com.

In 1998, Danza won the People's Choice Award for Favorite Male Performer in a New Television Series for his work on the 1997 sitcom The Tony Danza Show.

When Danza was 14, he and his family relocated to Malverne, New York on Long Island. Danza attended Malverne High School, graduating in 1968. In the first episode of his show "Teach: Tony Danza", Danza describes himself as a "bad student" in high school. Danza earned a bachelor's degree in history in 1972 from the University of Dubuque, which he attended on a wrestling scholarship. It was during his first year of college that he got the Robert Crumb Keep on Truckin' tattoo on his upper right arm. In a 1985 interview in Us Weekly magazine, Danza remarked, "I was playing pool with a guy who had all these tattoos, and I wanted to be friends." Danza sports a "Keep Punching" boxing gloves tattoo on his right shoulder. In college, Danza met and married his first wife. Danza was a professional boxer with a 9-3 record, with all of his fights, wins and losses, ending by knockout.
