Created around fifteen years ago as an extracurricular activity in order for interested students to learn more about television production, Blair Network Communications has evolved into a student-run multimedia organization and academic class that serves the Montgomery Blair and greater Silver Spring community in a variety of ways. Blair Network Communications, more commonly known as BNC, was founded under the name WBNC under the guidance of Blair media teacher Christopher Lloyd, who would continue to advise, along with fellow teacher, Mr. John Goldman, the student leaders of the organization for the next thirteen years. After several years of existence merely as an after-school commitment, interest in BNC's activities and demand to join became such that it was changed from an extracurricular to a course offered during the school day. 

During the 1990s, BNC produced a wide variety of radio and television shows with the television products created to air on Montgomery County Public Schools' municipal cable channel. Show topics ranged from issues that parents of students at different school levels face, events and topics of interest to the Blair community, life in the metropolitan Washington, D.C. area and educational material specially targeted at small children. During this time period, students on the BNC staff produced a total of six different shows, some of which were broadcast live. 

Over its fifteen years of existence, BNC has received significant media attention and even media accolades for its achievements, most significantly for the controversy that surrounded a television production called Shades of Grey, one episode of which focused on the contentious issue of gay marriage. As a result of the controversial subject material, Montgomery County Public Schools refused to air the episode of Shades of Grey, but later allowed the show to go on after a long battle with the school board and county school superintendent. 

Until 2001, BNC's central structure revolved around the television production aspect of the organization, but afterward, the format of the staff was modified. At that point, the organization was divided into four divisions with an Executive Director for each – Television, Radio, Production Engineering and Internet, the last of which was created as an offshoot from the Engineering for Network Technology position. The last division, Public Relations, was created a year later in order to publicize all of BNC's products and upcoming events. BNC also experienced a change in teacher leadership during the 2003-2004 production year after longtime advisor Christopher Lloyd decided to leave, and was replaced with television production teacher Shay Taylor. 

The 2006-2007 production year marks significant changes in BNC. BNC will be broadcasting its shows live from the studio again after almost 10 years. A new show has also been introduced into the lineup, borrowing elements from Shades of Grey as a talk show about prevalent issues in high school, aptly named Shades of Life. 

Today, BNC produces one 1-hour and two 29-minute show broadcast live about a wide variety of topics in addition to the daily six-minute morning announcements show. The organization also supports and creates radio shows, live streaming of various BNC and Blair events as well as other special projects like the Blair Educational Network, all of which make a great contribution towards the school community.
