In 1994, the Brady Campaign was at the height of its power and they drew huge crowds of reporters wherever they went, and groups like the Million Mom March were picking up lots of steam. The media always plays on the fears of the people, and during the innocent Clinton years there wasn't much to seriously be afraid of, so guns were a convenient target.
Today, the anti-gun groups are much weaker. Sebastian from Pro-Gun Progressive gave a firsthand account of a Brady press conference where only 3 non-Brady staffers attended in this blog post:

But the Internet really sheds light on the disparities between the two sides: I know of more than 100 blogs that are dedicated to gun discussion and pro-gun advocacy, and 3 blogs that are dedicated to gun control advocacy, and 2 of those anti-gun blogs (the Brady blog and Gun Guys) are written by paid lobbyists. Most amusing is that the Bradys disabled comments on their blog posts after the comments began running 30-to-1 against them. Before the Web took off, people were much more dependent on the anti-gun MSM for public policy information.
