Marketing majors may also stand to have the most fun, says Michelle Tennant Nicholson, chief creative officer at publicity firm Wasabi. "I think Darrin from the TV series " Bewitched" had the most fun, especially when his mother-in-law Endora involved her magic," Nicholson says. "I'd have to vote for marketing professionals as having the most day-to-day job enjoyment. I mean, come on. Social media today is too much fun, is it not? Interacting directly with an audience is so exciting." When it comes to earning power, Nicholson says that a major in advertising may be too restrictive. "I've seen this industry transition from typewriters to Twitter. In today's digitally driven world, you need to have proficiency in earned, owned and paid media to really advise your clients well around marketing strategy. Advertising only limits earning potential, from my perspective," she says. In the right company, the right marketing job can land you a ton of money, Harbron says. "A top-class marketing director in the U.S. can earn up to $150,000 to $200,000 per year, and that's in a medium-sized company. There are various types of marketing though, and for this top-dollar amount, you'll be working your socks off."
