1. It's unlikely that Prince George of Cambridge munched on Domino's Pizza at his first birthday party today, but that didn't stop the American pizza chain from playfully trying to cash in on the royal celebration.

    Royal trend watchers call it "The Prince George Effect." It encompasses everything from the media frenzy that has surrounded all of George's public appearances last year to his fashion sense and debates surrounding infant car-seat safety

    After all, the tiny royal's stamp of approval can mean big business. Just ask Petit Bateau, the French makers of the dungarees worn by George in his official birthday portraits released this week by the Royal Family. The company has sold out of the dungarees, which retail at €43 a pair, according to French newspaper L'Express.
  2. Marmite, the classic British spreadable known for its tagline "Love it or hate it" and distinct, polarising taste also tweeted birthday wishes to George. With a "toast for the Baby One," the brand managed to tout its own line of "Baby One" Marmite bottles alongside a special edition "Ma'amite" created to celebrate the Queen's Diamond Jubilee in 2012.
  3. Other businesses also tried to capitalize on the pint-sized royal's first birthday.
  4. But, businesses aren't the only ones benefiting from The Prince George Effect. As some have suggested, the Royal Family itself may be capitalizing on the positive publicity brought about by baby George. Even Vanity Fair celebrated the chubby-cheeked heir's birthday by putting him on the front cover, touting the prince as a "media star, style icon and PR triumph."

    His birthday even came with a bespoke hashtag #HappyBirthdayPrinceGeorge.
  5. Prince William and Kate, the Duchess of Cambridge asked that no gifts be sent to mark George's birthday and released a statement thanking people for "their warm and generous good wishes to George and our family." The family celebrated with a low-key gathering at Kensington Palace, attended by George's great-grandmother, Queen Elizabeth II, and other royal family members. 

    Well-wishers from around the world tweeted to the one-year-old royal to virtually join in the family's celebrations.
  6. A few people even celebrated the George's birthday with cakes and toasts of their own.
