Question:
Bloggingheads.tv (sometimes abbreviated "bhtv") is a political, world events, philosophy, and science video blog discussion site in which the participants take part in an active back and forth conversation via webcam which is then broadcast online to viewers. The site was started by the journalist Robert Wright (The Evolution of God, Nonzero: The Logic of Human Destiny, The Moral Animal) and the blogger and journalist Mickey Kaus on November 1, 2005. (Kaus has since dropped out of operational duties of the site as he didn't want his frequent linking to be seen as a conflict of interest.) Most of the earlier discussions posted to the site involved one or both of those individuals, but since has grown to include a total of over one thousand individual contributors, mostly journalists, academics, scientists, authors, well known political bloggers, and other notable individuals.
Although most episodes and matchups do not occur on any kind of a regular basis, there are a few notable exceptions to this. There is a frequent (previously biweekly and weekly, but now less frequent) diavlog matchup between the two co-founders of Bloggingheads.tv, Robert Wright and Mickey Kaus, generally related to politics in some form, that usually occurs on either Wednesday or Thursday. While some of the other diavloggers are frequently matched against each other (e.g. David Corn & James Pinkerton) there is usually not a regularly scheduled time at which they take place.  "Science Saturday" was the name given to the weekly episode appearing on Saturday that was always science related. Its last episode was released on December 24, 2011. It usually (but not always) involved either one or both of the science writers John Horgan and George Johnson. Many well-known people in the science community were a part of Science Saturday, including Michael Shermer of Skeptic Magazine, biologist PZ Myers, Craig Venter of the Human Genome Project, aging researcher and biogerentologist Aubrey de Grey, and philosopher David Chalmers, among many others. However, in September 2009, four high-profile science bloggers who had previously participated in Bloggingheads.tv discussions publicly distanced themselves from the site and stated they would no longer agree to appear in Bloggingheads.tv segments. The scientists - Sean Carroll, Carl Zimmer, Phil Plait and PZ Myers - all criticized what they claimed was a policy by Bloggingheads.tv to provide a platform for the anti-scientific ideology, Creationism without an opposing point of view for balance. PZ Myers said: "[Bloggingheads.tv] was setting up crackpots with softball interviews that made them look reasonable, because their peculiar ideas were never confronted."  "The Week in Blog" was a weekly segment which normally appeared on the site on Fridays. Its last episode was released on March 7, 2012. The format was to discuss what has showed up on the past week on both liberal and conservative blogs, from both a liberal and conservative viewpoint. The three regular hosts of "TWIB" were Bill Scher of Liberal Oasis, Kristin Soltis of the Winston Group, and Matt Lewis of The Daily Caller. Original host Conn Carroll of The Heritage Foundation stepped aside in early 2009. Guests who appeared on the show are Armando Llorens (of Daily Kos), Amanda Carpenter, and Nate Silver (of FiveThirtyEight) among many others.

Answer the question at the end by quoting:

Cary Grant (born Archibald Alec Leach; January 18, 1904 - November 29, 1986) was an English-American actor, known as one of classic Hollywood's definitive leading men. He began a career in Hollywood in the early 1930s, and became known for his transatlantic accent, debonair demeanor, and light-hearted approach to acting and sense of comic timing. He became an American citizen in 1942. Born in Horfield, Bristol, Grant became attracted to theatre at a young age, and began performing with a troupe known as "The Penders" from the age of six.
Stirling refers to Grant as "one of the shrewdest businessmen ever to operate in Hollywood". His long-term friendship with Howard Hughes from the 1930s onward saw him invited into the most glamorous circles in Hollywood and their lavish parties. Biographers Morecambe and Stirling state that Hughes played a major role in the development of Grant's business interests, so that by 1939, he was "already an astute operator with various commercial interests". Scott also played a role, encouraging Grant to invest his money in shares, making him a wealthy man by the end of the 1930s. In the 1940s, Grant and Barbara Hutton invested heavily in real estate development in Acapulco at a time when it was little more than a fishing village, and teamed with Richard Widmark, Roy Rogers, and Red Skelton to buy a hotel there. Behind his business interests was a particularly intelligent mind, to the point that his friend David Niven once said: "Before computers went into general release, Cary had one in his brain". Film critic David Thomson believes that Grant's intelligence came across on screen, and stated that "no one else looked so good and so intelligent at the same time".  After Grant retired from the screen, he became more active in business. He accepted a position on the board of directors at Faberge. This position was not honorary, as some had assumed; Grant regularly attended meetings and travelled internationally to support them. His pay was modest in comparison to the millions of his film career, a salary of a reported $15,000 a year. Such was Grant's influence on the company that George Barrie once claimed that Grant had played a role in the growth of the firm to annual revenues of about $50 million in 1968, a growth of nearly 80% since the inaugural year in 1964. The position also permitted use of a private plane, which Grant could use to fly to see his daughter wherever her mother, Dyan Cannon, was working.  In 1975, Grant was an appointed director of MGM. In 1980, he sat on the board of MGM Films and MGM Grand Hotels following the division of the parent company. He played an active role in the promotion of MGM Grand Hotel in Las Vegas when opened in 1973, and he continued to promote the city throughout the 1970s. When Allan Warren met Grant for a photo shoot that year he noticed how tired Grant looked, and his "slightly melancholic air". Grant later joined the boards of Hollywood Park, the Academy of Magical Arts (The Magic Castle, Hollywood, California), and Western Airlines (acquired by Delta Air Lines in 1987).
