W1WX is Boston's second television station (the first being W1XAY). This station started up in April 1929, and was owned by Shortwave and Television Laboratory, Inc., (which was founded on December 5, 1928 by A.M. "Vic" Morgan, Hollis Baird, and Butler Perry). The station started off broadcasting on 2120 kHz, alternating between 48 and 60 vertical lines and 15 frames per second. In 1930, it moved over to 2.1-2.2 kHz and broadcast at 48 lines only, still at 15 frames per second. In 1934, the station switched back to 60 vertical lines only, running at 20 frames per second until it shut down. Timeline - April 1929: Station is founded as W1WX by Shortwave and Television, broadcasting two times a day at 100 watts power, until December.

Included was what is sometimes called the first television commercial, which was prohibited by FRC regulations, however, other experimental television stations such as W1XAY may have done so before W1XAV signed on the air. Regardless, the FRC advised against this, since there was no agreement on whether experimental stations could air commercials, or sponsored network programming.
