Toys “R” Us developed a great holiday promotion that encouraged more customers to become fans on the company’s Facebook page.

Using standard e-mail and other traditional marketing channels, the company let customers know they’d receive specific holiday discounts by agreeing to fan the company on Facebook.

In the end, it was very successful.

How successful?

When the promotion was at its peak, it generated as many as 90,000+ new fans a day.

(It’s also worth noting that Toys “R” Us’ December sales were up almost 5% in 2009, while a lot of competitors were struggling as the recession had a huge impact.)
