Blonder Tongue Laboratories isn't involved in genetic modification -- it makes equipment for acquiring and distributing cable TV signals. Founded by Isaac Blonder and Ben Tongue, the company's offerings center on analog and digital video products for headend facilities (television signal-receiving centers), such as encoders, receivers, and modulators, as well as hybrid fiber-coax (HFC) distribution products, which deliver the signal to the viewer. Blonder Tongue mainly serves cable operators, TV broadcasters, the lodging and hospitality sector, and institutional facilities such as schools, hospitals, stadiums, airports, and prisons.
