BLACK SOCIAL HISTORY : BILL COSBY RISE AND RISE IS DUE TO EXCEPTIONAL TALENT AND AS A BLACK PERFORMER IS SECOND TO NONE :

In 1965, when he was cast alongside Robert Culp in the I Spy espionage adventure series, Cosby became the first African-American co-star in a dramatic television series, and NBC became the first to present a series so cast. At first Cosby and NBC executives were concerned that some affiliates might be unwilling to carry the series. At the beginning of the 1965 season four stations declined the show; they were in Georgia, Florida, and Alabama.^{[citation needed]} Viewers were taken with the show's exotic locales and the authentic chemistry between the stars, and it became one of the ratings hits of that television season. I Spy finished among the twenty most-watched shows that year, and Cosby would be honored with three consecutive Emmy Awards for Outstanding Lead Actor in a Drama Series.
During the run of the series, Cosby continued to do stand-up comedy performances and recorded a half-dozen record albums for Warner Bros. Records. He also began to dabble in singing, recording Silver Throat: Bill Cosby Sings in 1967, which provided him with a hit single with his recording of "Li'l Ole Man". He would record several more musical albums into the early 1970s, but he continued to record primarily stand-up comedy work.
In June 1968 Billboard reported that Cosby had turned down a five-year, US$3.5 million contract renewal offer and would leave the label in August that year to record for his own record label.
Tetragrammaton Records was a division of the Campbell, Silver, Cosby (CSC) Corporation, the Los Angeles based production company founded by Cosby, his manager Roy Silver, and filmmaker Bruce Post Campbell. It produced films as well as records, including Cosby's television specials, the Fat Albert cartoon special and series and several motion pictures. CSC hired industry veteran Artie Mogull as President of the label and Tetragrammaton was fairly active during 1968–69 (its most successful signing was British heavy rock band Deep Purple) but it quickly went into the red and ceased trading during 1970.

Cosby pursued a variety of additional television projects and appeared as a regular guest host on The Tonight Show and as the star of an annual special for NBC. He returned with another series in 1969, The Bill Cosby Show, a situation comedy that ran for two seasons. Cosby played a physical education teacher at a Los Angeles high school. While only a modest critical success, the show was a ratings hit, finishing eleventh in its first season. Cosby was lauded for using some previously unknown African-American performers such as Lillian Randolph, Moms Mabley, and Rex Ingram as characters. According to commentary on the Season 1 DVD's for the show, Cosby was at odds with NBC over his refusal to include a laugh track in the show (he felt that viewers had the ability to find humor for themselves when watching a TV show). He was originally contracted with NBC to do the show for two seasons, and he believes the show was not renewed afterwards for that reason.
After The Bill Cosby Show left the air, Cosby returned to his education. He began graduate work at the University of Massachusetts Amherst, qualifying under a special program that allowed for the admission of students who had not completed their bachelor's degrees, but who had had a significant impact on society and/or their communities through their careers. This professional interest led to his involvement in the PBS series The Electric Company, for which he recorded several segments teaching reading skills to young children.
In 1972, Cosby received an MA from the University of Massachusetts Amherst and was also back in prime time with a variety series, The New Bill Cosby Show. However, this time he met with poor ratings, and the show lasted only a season. More successful was a Saturday morning show, Fat Albert and the Cosby Kids, hosted by Cosby and based on his own childhood. That series ran from 1972 to 1979, and as The New Fat Albert Show in 1979 and The Adventures of Fat Albert and the Cosby Kids in 1984. Some schools used the program as a teaching tool, and Cosby himself wrote a dissertation on it, "An Integration of the Visual Media Via 'Fat Albert And The Cosby Kids' Into the Elementary School Curriculum as a Teaching Aid and Vehicle to Achieve Increased Learning", as partial fulfillment of obtaining his 1976 doctorate in education, also from the University of Massachusetts. Subsequently, Temple University, where Cosby had begun but never finished his undergraduate studies, would grant him his bachelor's degree on the basis of "life experience."
Also during the 1970s, Cosby and other African-American actors, including Sidney Poitier, joined forces to make some successful comedy films that countered the violent "blaxploitation" films of the era. Uptown Saturday Night (1974) and Let's Do It Again (1975) were generally praised, but much of Cosby's film work has fallen flat. Mother, Jugs & Speed (1976) costarring Raquel Welch and Harvey Keitel; A Piece of the Action, with Poitier; and California Suite, a compilation of four Neil Simon plays, were all panned. In addition, Cos (1976) an hour-long variety show featuring puppets, sketches, and musical numbers, was canceled within the year. Cosby was also a regular on children's public television programs starting in the 1970s, hosting the "Picture Pages

" segments that lasted into the early 1980s.
