No matter how much money Microsoft throws at its advertising campaign, it seems Apple is still beating it with its "Get a Mac" commercials.

A recent study by Visible Measures shows that even though Microsoft's ads "I'm a PC" had initial success, the new Apple ads, "Bean Counter", "V word" and "Bake Sale," together took over the top spot in viral video views. The first week of the study did show "I'm a PC" with 1.5 million more viewers, some say its due to the curiosity of how Microsoft will compete against Apple's advertising monster. The new "Get a Mac" ads push did however move their way back into url views to give Apple a wider coverage and a commanding lead. Microsoft may need to invest in some better advertising or use the money to make a better operating system, either way, it will be a challenge to dethrone Apple's current marketing campaign.
