Man, this Online DVD rental thing is getting to be as big as Blogging! The Industry Standard is reporting that Amazon has entered the whole Online DVD rental market in the UK.

Now I have to wonder, will all of these companies that are competing so aggressively still be as active when the new DVD-Media rolls out? I would be interested to see how HD-DVD and Blu-ray contribute to this situation.

Amazon.com Inc. dipped its toes in the online DVD rental market this week with the launch of a service in the U.K. The online retail giant introduced two monthly plans on Thursday for renting DVDs at its Amazon.co.uk site, as it made its anticipated move into the market.

U.K. consumers can sign up to have four DVDs of their choice delivered to their homes for �7.99 (US$15.40) a month, or six DVDs for �9.99 a month. The DVDs are delivered in batches of two or three, depending on the plan, and users aren’t charged late fees. Subscribers send the DVDs back in a prepaid envelope to receive their next batch.

The service is similar to Blockbuster Inc.’s U.K. service, although Blockbuster offers unlimited DVD rentals for �13.99 a month. The number of movies subscribers can rent depends on how fast they watch them and send them back to get their next batch.

Blockbuster’s service mirrors that of U.S. market leader Netflix Inc., which offers unlimited rentals for $17.99 a month.
