The tough decisions for electronics consumers usually have to do with formats. A shopper decides to by a new DVD player, but is faced with several formats that are competing. These formats affect everything else, from the type of television the consumer buys to the types of movie DVDs they buy. If one format outweighs the other in consumer demand, that format will be preferred in all related products. Therefore, if the consumer chooses the format that "loses out," they're just out of luck!

Another example from the video electronics industry is formatting for televisions. There is HDTV, SDTV and Blu-Ray. Other formats are sure to pop up eventually. Buying an HDTV also means buying a new DVD player with HDTV compatibility.

Consumers can avoid format wars somewhat by waiting a while before making a purchase. They don't have to rush out and buy the latest audio or video product. There's no need to buy the brand new cell phone with all latest features. Music equipment can usually wait as well.

If consumers can wait a little while before buying, the best format will be revealed by consumer demand and the number of related products that will support that particular format. If an electronics product is released in fall, consumers can wait until the following spring before buying. When waiting is not possible, research can help. The Web offers a wealth of information on just about any product.
