From an original estimate of about $400 million, by the time of launch it had cost $2.2 billion and by today has probably cost twice that amount.
It was named after the famous scientist Edwin P. Hubble (1889-1953) because he was the one who made the discovery that our universe was expanding. The space telescope designed to replace Hubble around 2018 is named for the late NASA administrator James Webb (1906-1992).
launch delays, budget problems and a incorrect mirror
The Hubble telescope was the first telescope built by NASA and placed into orbit. The original launch for the telescope was delayed because of the disaster seen by the Challenger.
At this time (early 2014), the James Webb Space Telescope is scheduled to launch during October of 2018 .
The James Webb telescope is on track for a planned launch in the year 2013.
No. It's scheduled for launch in 2018.
The James Webb Space Telescope is scheduled for launch in 2018. The Webb telecope is not a direct replacement for the Hubble. The Hubble has been so reliable since its launch in April, 1990, that it's expected to function through 2014, and possibly as long as 2020.
The James Webb Space Telescope (JWST) is the planned successor of the HST and the Spitzer Space Telescope (for observations in infrared). It will have a diameter of 6.5 m (the HST has 2.4 m). As of now, the launch will be in 2017 or 2018.

The replacement for the Hubble is called the James Webb Space Telescope.

The successor of the HST shall be the James Webb Space Telescope (JWST).

If the Hubble is still working by the time Webb is launched then yes. The Webb is not a replacement, but a successor.
