 Maryland Public Television - Old Name - 
Maryland Center For Public Broadcasting


Maryland Public Television (MPT) (formerly the Maryland Center for Public Broadcasting) is a not-for-profit, state-licensed public television network which serves U.S. state of Maryland. Its six transmitters cover nearly all of the state, plus Washington, D.C. and parts of Virginia, West Virginia, Delaware and Pennsylvania.

MPT's local and regional television credits include several state-focused programs on civic and public affairs, as well as a variety of original performance, documentary, and entertainment offerings for the citizens of Maryland. Beyond broadcasting, MPT creates instructional videos, develops training, and builds Internet sites that serve tens of thousands of students, teachers, and child-care providers annually. The centerpiece of MPT's service to Maryland educators, students, and families is Thinkport, a Web site that offers online teaching resources, professional development opportunities and digital technology tools to assist educators.

Maryland Public Television has earned awards ranging from television Emmys for its quality productions to government citations for its volunteerism and educational accomplishments. Since 1969, MPT has broadcast an analog signal from transmission towers throughout Maryland, and now provides digital transmission as well. In February 2000, the network's first digital signal began from MPT's transmitter in the Annapolis/Crownsville area. MPT has been led by Robert J. Shuman, president and chief executive officer, since 1996. It operates under the auspices of the Maryland Public Broadcasting Commission and benefits from the support of an affiliated 501(c)(3) organization, the MPT Foundation, Inc. (formerly known as the Maryland Public Broadcasting Foundation, Inc.)

 Analog-to-digital conversion

After the analog television shutdown on June 12, 2009:[1]

  • WCPB and WGPT returned to channels 28 and 36, respectively;[2][3]
  • WMPB, WMPT, WWPB, and WFPT remained on their respective, pre-transition channel numbers (29, 42, 44, and 28).[4][5][6][7]

Through the use of PSIP, digital television receivers display virtual channels for each MPT station corresponding to their previous analog channel numbers.
