Amazon Prime viewers got a nice surprise on Wednesday, after the online retailer announced that it had struck a deal with Discovery Communications for the rights to stream popular TV shows such as “Dirty Jobs” and “Say Yes to the Dress.”

The deal is just the latest in the company’s efforts to bulk up its offerings to compete against Netflix, and the addition of 3,000 Discovery titles brings Amazon’s total count up to 17,000, according to Amazon’s release.

Amazon Prime costs $79 a year and gives users unlimited access to instant video, plus free and discounted shipping.

“With the addition of this great content from Discovery Communications, Prime customers now have more than 17,000 titles to choose from when watching Prime Instant Video,” Amazon’s director of video content, Brad Beale, touted in a statement. “That’s in addition to the more than 120,000 titles that are offered to all customers for purchase or rent on Amazon Instant Video.”

Netflix, which doesn’t release the number of titles it offers, is said to have around 13,855 titles, according to a report from VentureBeat. The streaming video space is getting more crowded and more accessible. Walmart recently announced that it would be offering customers the chance to convert their regular DVDs to digital copies through its Vudu service.
