If you're looking to become hooked into a stellar TV series then Lost would be one of my first recommendations. The storyline is deep with excellent character development and lots of surprises. With 121 episodes that make up six season, you'll have plenty of content to enjoy before finishing the series. Lost is the type of series that you'll want to watch from the beginning and continue in sequential order so it will be near impossible to enjoy its greatness unless you buy the seasons in DVD form or stream/buy them via the following online services:

All six season of Lost are available for unlimited streaming via the subscription service, Netflix. All you need to do is pay the flat fee of $7.99/month (no long-term commitment required) which provides instant access to shows like Lost, Prison Break, Dexter, Breaking Bad, and many more at no additional cost. One of the biggest advantages to Netflix is their free 30-day trial period which offers the full streaming benefit without paying a dime (valid credit card required). This way you can test out the service for the first month which is more than enough time to watch the first seasons or two of Lost then cancel if you are not content with the service.

If you're looking to stay away from a monthly subscription service, you can always buy each episode or seasons via Amazon's Instant Video service for a low-cost per episode. They offer all six seasons in both high-definition and standard definition. For example, the HD episodes are available at $2.99 per episode ($1.99 for SD) and each season is available in discounted bundles.

Apple is currently offering all six seasons of Lost in their iTunes Store with a similar pricing structure to Amazon's Instant Video offering. You can pay $2.99 per HD episode or buy the full seasons for a discounted bundle. This option is ideal for those who want to use their iPhone or iPad for watching episodes.

Vudu is not as well-known as the other options listed here, but it is still a reputable source that offers a great deal of video content. Within the Vudu library, you'll find all six seasons of Lost in your choice of standard definition, high-definition, and HDX which features full 1080P HD as well as Dolby Digital Plus 7.1 surround sound.
