Apple

Apples had a large effect on the economy by inventing and developing a different computer operating system that many consumers think is more efficient and durable and also less prone to being corrupted malicious viruses. Because of this new invention and competition it caused Microsoft to drop their prices for many of the computers and software that they produce and sell to maintain a high level of sales because the Mac is widely considered a better product. Even during an economy marred in the 4th quarter of 2009 by layoffs, bankruptcies and bailouts; Apple managed to get record revenue and sell a record number of Ipods. This success not only was a positive effect on the employees of Apple, but also the thousands of people who invested in its stock. Apple got 46% of its revenue from international states. This has helped Apple to stay in the forefront of inventing new technology, which improves the efficiency of how many businesses process information, and therefore has a positive effect on the economy also.
