WYBE's main channel was previously carried in the New York City television market on the 66.4 digital subchannel of West Milford, New Jersey–licensed MHz WorldView affiliate WNYJ-TV.

Metropolitan Philadelphia Educational Radio and Television, owner of WHYY, continued to operate channel 35 as WUHY-TV, using it mostly to air instructional programming on weekdays (outside of designated legal and administrative holidays) during the school year.

[5] In the 1980s, the channel 35 frequency was used by W35AB, a translator relaying Univision programming from New York City's WXTV, while the FCC evaluated applications for a new permanent licensee.

Several of these programs won national Telly Awards, Emmy nominations and a special screening at the Philadelphia International Gay & Lesbian Film Festival.

On April 13, 2017, Independence Public Media of Philadelphia, Inc. announced that it gave up its broadcast license as WYBE (channel 35), and would sign off the air on November 3, 2017.

Prior to its planned termination date, MiND TV went temporarily off air due to the equipment at the WYBE transmitter site having failed, according to the channel's website, but would be restored on November 1, 2017.

The WYBE license was transferred to the Lehigh Valley Public Telecommunications Corporation, owner of WLVT-TV, on March 15, 2018; concurrently the call letters were changed to WPPT.
