Liam Neeson, Pierce Brosnan Are Top TV Pitchmen

— -- What do Liam Neeson, Pierce Brosnan, Sofia Vergara and Jennifer Garner all have in common?

They are the best celebrity endorsers in the game, according to Nielsen, the market research company that also measures TV ratings.

Nielsen's first "N-Scores" were released Tuesday. The company looked at celebrities who made commercials during the first three months of the year and ranked them with a calculation that takes into account likability, public awareness, influence and other factors.

Neeson, who starred in the hit film, “Taken,” emerged the top salesman and fan favorite pitchman. Brosnan, who has played James Bond in the popular film franchise, was a very close second.

Jeff Bridges stood out among celebrities for the amount of influence he carried with his fans, Nielsen said.

The "N-Scores" will directly compete with Marketing Evaluations Inc.'s better-known Q Score, a measurement of public attitudes toward well-known figures.

Adweek’s Jesse Oxfeld offered analysis of the N-Scores.

“Some of the highest-ranking people are people like Liam Neeson and Jeff Bridges -- men of a certain age,” he told ABC News. “I think part of what you’re seeing there is gravitas and some trustworthiness, but I think it’s also reflecting the fact that baby boomers are really the biggest consumer demographic.”

Other celebrities with recent ads that scored well in Nielsen's measurement were Natalie Portman, Matthew McConaughey, Jim Parsons, Dennis Haysbert and J.K. Simmons.
