Many companies are finding that old titles are once again becoming profitable. Companies such as Atari are active in protecting its older arcade titles from illegal distribution and many companies are re releasing older titles in toy joystick or game packs that plug into a regular TV.
Much of the abandonware that you can find online is free to download from the host sites, but the copyright holder isnt always aware of this free distribution. Many abandonware sites such as Home of the Underdogs, post a disclaimer stating any copyright holder requesting a game removed, will have that request granted.
