ABC and CBS said Monday they would offer gavel-to-gavel coverage of the Democratic and Republican conventions this year over the Internet as well as periods of prime-time coverage over their broadcast networks.
Both ABC News and CBS News will offer one hour of prime-time coverage on three nights of each convention.
Last week, NBC said it would offer one hour of prime-time coverage each night of both conventions, supplemented by five hours of coverage each night on cable channel MSNBC.
Political conventions have become staged ``publicity making machines'' for both parties and thus inappropriate for the television networks to cover to the extent they once did, ``Nightline'' host Ted Koppel told the Television Critics Association Monday.
Koppel walked out of the Republican convention in 1996 and did not attend the Democratic convention that year to ``make a statement that conventions had significantly changed,'' he said.
But both he and ``World News Tonight'' anchor Peter Jennings said it was proper to use new technology to bring more extensive coverage to those who want it.
