Who's on top of 101 most influential imaginary icons

They are not real, but they influence our lives.

And topping a list of "The 101 most influential people who never lived" in a book released on Tuesday is the Marlboro Man -- a macho American cowboy who emerged in the 1950s and helped boost sales of Marlboro cigarettes.

"The figments of our imaginations, the creatures we push out of our minds into the real world are fully capable of pushing back with surprising consequences," told Jeremy Salter, one of the U.S. book's three authors.

King Arthur

Coming in at number two on the list is Big Brother of George Orwell's 1984, followed by King Arthur, who the authors say embodies for many the ideal monarch, and Santa Claus comes in at number four.

"Santa Claus governs our entire economy for the last quarter of the year and without him businesses would go broke," said co-author Allan Lazar.

Barbie "the bodacious plastic babe who became a role model for millions of little girls, setting an impossible standard for beauty and style" makes the list at number 43.

But Rosie the Riveter, the buff, blue-collar factory worker who the authors say helped jump-start the women's liberation movement comes in at 28.

"The idea came to us that influential characters didn't have to exist, that fictional characters were just as important in our lives, even in maybe some cases more so than real people," said Lazar.

Even the Loch Ness Monster makes the list at number 56.

"As the most popular tourist attraction in Scotland, Nessie's influence on the cash flow of that country has been significant," wrote the authors of "The 101 most influential people who never lived."

Paul Bunyan

At 101 was Paul Bunyan, a mythical lumberjack who the authors say was created by U.S. lumberjacks during the 1800s "to bring some good cheer, and esteem into their lives of drudgery."
