In great detail, what are the similarities and differences between the television shows Roseanne and Will and Grace in terms of aesthetic, social implications, possible technical achievements, and relevance to its particular audience?

The similarities between the very popular television sitcoms Roseanne (which ran from 1988-1997) and Will and Grace (which ran from 1998-2006) are that they both focused on segments of the American population that are not always in the television limelight. Behind the laughter they sought to generate, the shows publicized real social issues.
Roseanne dealt with the travails of the working class and their struggles to make a living. Roseanne Conner, a working parent, has many jobs in the show, including initially working in a plastics factory and later working as a waitress and as the owner of a motorcycle repair shop. Her blue collar family and friends struggle with unplanned pregnancies, physical abuse, and illness, and the main characters are noticeably un-Hollywood (some are overweight and decidedly unglamorous). The aesthetic is Mid-American, with a plaid couch and cozy afghan center stage in the Conner family's living room. The show was one of the first that was relevant to working-class Americans and that portrayed their lives and struggles in a sympathetic way, and the show also featured openly gay characters, such as Jackie, who is a lesbian.
Will and Grace is about a Jewish interior decorator who lives with her best friend, a gay lawyer. The show was one of the first to sympathetically portray the life of a gay main character, Will, who struggles at times to tell people about his sexuality. The aesthetic of the show is quite different than that of Roseanne, as Will and Grace live in a very sophisticated, expensive New York City apartment and have glamorous clothes and lives. The show was relevant to the LBGTQ community, as it humanized the lives of gay people and showed their relationships in a sympathetic way. Will and Grace also received several technical awards for film editing, production design, and costume design. Its sets and costumes were far more lavish than those of Roseanne.
