Now the economic sector has sunk, and is it worth buying shares, if so, in which area? I am considering buying shares of any Internet publications and large companies, is there a demand for them and will there be an increase in shares?
There are lots of books out there on the topic of investing in the stock market, you really have to get out there and start reading them yourself to make sense of it all. In the short term you likely want to look for the lowest cost broker of index funds, which are effectively large baskets of stocks which will help to diversify the risk away. Buying shares in individual companies when you don't know the basics is a recipe for losing all your money. Learn first and act later.
