#6. AOL Buys Netscape
When AOL (AOL) purchased web browsing platform Netscape, it was a force to be reckoned with. But now AOL is struggling, and Netscape went from a dominant a market share of more than 90% to effectively zero in the decade after the deal.
Still, Netscape engineers went on to create the Mozilla Firefox browser and founder Marc Andreessen has gone on to play a prominent role as an investor in other internet stocks, including current online powerhouses LinkedIn (LNKD) and Twitter (TWTR) among others.
