If you're feeling good about the market, you're not alone. Take my hand as we go over some of this week's more uplifting headlines.

1. A bundle of celluloid joy
Amazon.com (NASDAQ:AMZN) has created a win-win situation with its latest digital bundle. The leading online retailer is marketing more than 300 of its DVD and Blu-ray titles as "Disc+ On Demand," through which it provides a digital copy of a purchased flick at no additional charge.

Some of the digital bonuses are rentals that expire within 24 hours of initiating playback, but others are actual files that last forever. Either way, Amazon is drumming up value in its already low disc prices with the freebies from its Video On Demand virtual storefront.

Amazon isn't a charity. Obviously, it's doing this because of the perceived upside for its digital video purchases and rental business. This has been a tough market to crack, but Amazon is one of the few companies that can juggle disc sales with streams for those seeking instant gratification.

2. Bring back that "Dell Dude" swagger
Dell (NASDAQ:DELL) has spent the past couple of years backpedaling, but it certainly seems to have gotten the swing of social media.

Dell's @DellOutlet Twitter page has 1.48 million followers, and the company's initiatives throughout Twitter have resulted in sales of $6.5 million. That may not seem like much for a company the size of Dell, but these are sales that have resulted from Dell's exploiting the viral nature of the free social-media site.

Dell's efforts have won it 3.5 million registered users across all social-media sites. Well played, Dell. Funneling Twitter users to closeout deals is genius. Hewlett-Packard's (NYSE:HPQ) main presence on Twitter is strictly a news page.

3. Yoga a-go-go
Well, at least affluent yoga enthusiasts are shopping again. lululemon athletica (NASDAQ:LULU) has some serious momentum heading into the telltale holiday season. The 119-unit fitness-apparel chain posted stellar results for its fiscal third quarter.

Revenue improved by 30%, propelled by an 11% increase in the number of stores and a healthy 10% spike in same-store sales on a constant-dollar basis. This is the first time lululemon has delivered positive comps in nearly a year.

Improving margins also helped earnings grow twice as quickly as the company's top line, with quarterly profits soaring by 60% to $0.20 a share. Even though this company is all about flashy and fancy workout duds, that's where the shoppers are right now.

4. Hasbro 1, Mattel 0
Let's just say Hasbro (NYSE:HAS) is the Cookie Monster, and Mattel (NYSE:MAT) is the cookie.

Om nom nom nom!

Hasbro is inking a 10-year deal with Sesame Street creator Sesame Workshop, and will introduce licensed toys into the marketplace come early 2011. Mattel is Sesame Workshop's current partner, perhaps best known for the Tickle Me Elmo doll that was all the rage several holiday seasons ago.

What will Hasbro cook up? Big Bird as its signature Mr. Potato Head? G.I. Elmo? Oscar the Grouch as a Transformer? Oh, come on. That last one is golden. Oscar is already partly housed in metal!

5. Endgame with style
Sirius XM Radio (NASDAQ:SIRI) is serving up more than just holiday-music specials. Once again proving its versatile appeal, the satellite-radio operator announced limited-engagement channels devoted to Snoop Dogg and the Second City comedy troupe.

The channels won't be around for long, though. Snoop Dogg's commercial-free channel will run for only a week and culminate in the release of the hip-hop legend's new album. The Second City channel will be up only for the weekend to commemorate the troupe's 50th anniversary.
