How come companies charge for downloads?
I am not an insider on the computer programming world, and if somebody is, please provide a more thurough answer. I can answer with this: Nothing is free. Companies charge for downloads because they need to cover the expenses to pay their employees (programmers, marketers, etc.). A common misconception is that the only reason people need to charge for software is the cost of selling it. However, any software, unless it is made for fun by a guy down in his basement, has production costs. Any program, even the ones that download free, such as iTunes, make money somewhere along the line. iTunes downloads for free, but makes money off the music store. Other programs, such as the weather tool Weather Bug, have a free version with ads, but have a subscription service with added benefits. If you are looking for a large selection of free (along with not free) downloads, head to Cnet's download.com. Hope that helps.
Some websites which offer karaoke downloads include Karaoke Version, The Karaoke Channel Store, TriceraSoft. These companies typically charge for their downloads, but free legal downloads are also available from other websites, such as a one called Free Karaoke which offers free karaoke songs in MIDI format.
How come instead of when you go to download it comes up as run it goes down to a little bar saying downloads on Google Chrome?
What do you call an agreement made between different companies to charge the same amount for products?
Half-Life and Doom were created by big companies that still exist today so free downloads are illegal. You are advised to get downloads from steampowered.com where they cost only about $10 each. If you are a dishonest jerk then you are advised to get free downloads from thepiratebay.org. If you are lucky, your computer won't be overrun by malicious viruses.
