[1] The network co-produced the long-running children's television series, Barney & Friends until the show (alongside other HIT Entertainment programs) were transferred to WNET.

The network's first station, WEDH in Hartford, signed on with a black and white signal in 1962, operating from a Trinity College library basement.

[citation needed] CPTV remained based in rented space at Trinity College until selling its headquarters back to the school for $10 million in 2002.

The infrastructure of CPTV was eventually upgraded through a partnership with Sony Systems Integration Center (SIC), which enabled the delivery of HD quality telecommunications to subscribers.

The character was discovered in 1991 when CPTV executive Larry Rifkin bought a Barney and the Backyard Gang home video for his daughter and was mesmerized by it.

WEDW is also available both over-the-air and on several cable systems in portions of Greater New York, including the non-bordering states of New Jersey and Pennsylvania.

Additionally, WEDH is carried by most cable systems in the Pioneer Valley of Massachusetts, providing a second choice for PBS programming alongside WGBY-TV in Springfield.

Finally, WEDN has wide over-the-air and cable availability in Rhode Island, including Providence (sharing the market with WSBE-TV and Boston's WGBH-TV/WGBX-TV).

[17] in 2009, leading up to the analog-to-digital television transition on June 12, CPTV shut down the analog transmitters of its stations on a staggered basis.

Since 2007, CPBN Media Lab instructors and mentors have provided real-world technical and journalism training for over 600 Connecticut students through seminars, workshops, and courses.
