There's a lot on the line this Sunday when the Patriots clash with the Falcons in Houston. Most important? Who will take home the win for best Super Bowl commercial.

The Super Bowl is appointment viewing each year for football fans, pitting the final two teams standing against each other to determine that season's NFL champion. But for non-football fans, the Super Bowl is also a must-watch experience, if for nothing else than the ads throughout the game.

How do you know that everyone will be watching? Just look at what advertisers are willing to pay to get their 30-second spot in front of a Super Bowl audience: Buying a 30-second spot will cost over $5 million on average, according to Variety.

While some advertisers wait to make their big reveal during the game and others come up with a unique plan on how to make every penny spent count (more on that in a minute), others make their ads available to watch before kickoff. Below is more on what you can expect to see on Super Bowl Sunday, as well as the best and worst Super Bowl commercials of all-time.

Commercials for Super Bowl LI

Top five Super Bowl ads ever

5. Volkswagen (2011)

Of all the more recent ad spots, this one sticks out:

Can you get any more adorable than a mini-Darth Vader trying to use The Force?

4. Budweiser (1989)

The first Bud Bowl was held during Super Bowl XXIII:

The spot would have seven sequels throughout the '90s in arguably the most memorable long-running ad campaign in Super Bowl history.

3. Apple (1984)

While not as sports-centric as most of the top ads on this list, there's no denying the debut of the Apple Macintosh its spot:

The Super Bowl spot was the only time Apple ran this ad, which is arguably among the top commercials of all time.

2. McDonald's (1993)

The fast-food company landed a pair of iconic NBA stars to battle over their burgers and fries:

I'd watch these two go at it in a head-to-head shooting contest today. Get on it, McDonald's.

Could it be anything else?

Worst Super Bowl ad ever

Fortune.com has a great list of terrible Super Bowl ads worth checking out. While many didn't work due to insensitive takes on race, death and other topics and deserve consideration, one was proud to declare itself the worst commercial ever. Despite having no reason to offend, Lifeminders.com is just that:

Unsurprisingly, the website didn't stick around for the long haul.
