Electronic equipment is everywhere in modern life. Both per capita ownership and discards of TVs, computers and other electronics will likely increase rapidly for a variety of reasons. For example, most electronic products, including flat panel displays for televisions and monitors, have become cheaper in the last few years. In June 2009 (previously February 2009), the television broadcast signal will change to a digital format which some older televisions will not be able to receive. Unwanted electronics should be recycled to recover and reuse the product itself or materials like copper, steel, glass that the product contains. Other materials like lead (in the solder on circuit boards; in the glass cathode ray tube (CRT) found in many televisions and computer monitors; in the batteries in uninterruptible power supplies) and mercury (in the fluorescent backlights in many flat panel displays) can be recycled to reuse the materials and to reduce the chance that these toxic materials could be released to the environment.
