Power up your laptop and secure an Internet connection. By far, the fastest way to find a vast and varied collection of old TV on DVD is by hopping online. The Web has become a great resource for old television, and you will find plenty of websites that offer cheap DVD collections.
Head to your nearest big-box retailer. Television on DVD has made a retail comeback in recent years, and nationwide stores such as Target and Wal-Mart have a surprisingly diverse selection of old TV favorites. Wholesalers like Sam's Club and Costco also have their fair share of ancient ****-tube glory.
Use your video rental store for buying, not renting. Sure, Netflix and Blockbuster Online are popular, but your local video store has plenty to offer. Video stores have to get rid of their stock eventually, and they are happy to hand over old TV on DVD for heavily discounted prices.
Dig through clearance bins. Hiding in that giant tub of 99-cent DVDs is a copy of "The Andy Griffith Show," "Three's Company" or "The Mary Tyler Moore Show." Whether you're at a bookstore, record store or dime store, the clearance bin almost always offers some good old TV.
Be patient. DVD sales are continually on the rise for old television and specialty shows. The market will not slow down anytime soon, and as long as there is an interested consumer, companies will continue to put old-time TV on disc.
