3-D cinema has been around since the early 20th century,but Hollywood brought the technology back in 2007. Many thought it was just a trick to make more money. But then came Avatar,the first mustsee movie in3-D.

But since Avatar,3-D cinema has struggled. In2010,several 3-D movies bombed at the box office. And by late 2010,some people said the technology was dead. Of course,this isn't the first time Hollywood has struggled with new tech?nology. Although sound was added to movies in the late 1920s,it took audience time to get used to the new technology. But in the end,sound and colour became the standard. James Cameron,director of Avatar,thinks we're going through the same process with 3-   D.

Some day cinemas are charging too much for 3-D movies. In the US,seeing a 3-D movie can cost up to $ 7. 5 more than seeing it in 2          D. Also,a recent study at the California State University has found audience don't actually enjoy movies in 3-D any more than in 2-   D. Walter Murch,a famous movie editor,wrote in 2011 that human beings have no ability to process 3-D images. Watching a 3-D movie confu?ses our brain and this is why some people get headaches.

But James Cameron disagrees. In fact,he recently predicted that in five years all movies will be in 3-   D. And there are signs that 3-D is fighting back. More 3-D movies were put on the market in 2012 than ever before. The Lion King3-D recently made over $ 150 million at the box office,and Cameron's Titanic3-D made even more.

Who knows what the future holds for 3-D? Steven Spielberg recently said, "I'm hoping 3-D gets to a point where people don't notice it because then it just be?comes another tool and helps tell a story."
