in the United States decades away, Zenith's prospects were not good. In 1995 LG, a giant Korean competitor, increased its stake to 55 percent, enough to assume controlling interest. Zenith was too small compete in the consumer electronics industry which had become global in nature, and its high-quality products made it attractive for acquisition. Zenith filed for Chapter 11 bankruptcy in 1999, and in exchange for its debts, LG bought the remaining 45 percent of the company, converting about $200 million of debt owed to it by Zenith into all the common stock of the revamped company. The shares of existing stockholders were rendered worthless. (During this era, some of Zenith's products were being rebadged as OEM under the Admiral name. Certain products also carried the Allegro brand (which originated in the 1970s as a brand for Zenith's speakers and other audio equipment).

Subscription television Zenith was the first company to experiment with subscription television, launching their Phonevision system with experimental Chicago station KS2XBS (originally broadcasting on Channel 2 before the Federal Communications Commission forced them to relinquish it to WBBM-TV). Their experiment involved a descrambler box mounted on the television set, and plugged into the telephone lead. When a preannounced broadcast was ready to begin, viewers would call an operator at Zenith who would send a signal with the telephone leads to unscramble the video. While the Theatre Owners of America claimed the concept was unsuccessful, Zenith itself claimed the experiment was a success. As Phonevision broadcast films, it was seen as a potential competitor for traditional theatres. In spite of the fact that the three films initially available to the first 300 test households were more than two years old, about 18 percent of Phonevision
