Macromedia used to be an independent company that created programs such as Dreamweaver, Fireworks and Flash. Their latest release was Suite 8, in about 2004.
In 2004/2005 Macromedia were bought by Adobe and so, now, Dreamweaver, Fireworks and Flash are all Adobe products.
The latest versions of the three programs are in Adobe Creative Suite 3 -- Adobe Dreamweaver CS3, Adobe Fireworks CS3 and Adobe Flash CS3.
