Various attractions have been part of Tomorrowland since the opening of Disneyland in 1955. A major renovation completed in 1959 added The Matterhorn (now part of Fantasyland), Submarine Voyage, The Disneyland Monorail and the renovation of The Skyway. Another major renovation in 1967 added The Peoplemover, Carousel of Progress, Flight to the Moon (a re-worked "Rocket to the Moon"), Rocket Jets and a new film, "America the Beautiful" in the Circlevision theater.

In 1974, America Sings replaced the Carousel of Progress, and Star Tours replaced Adventure Thru Innerspace in 1987. A 1998 update to Tomorrowland replaced the Peoplemover attraction with the Rocket Rods, and the Carousel Theater became Innoventions. 

In September of that same year, The Submarine Voyage was closed. In the year 2000, Chevron sponsored the new Autopia. The Fantasyland and Tomorrowland tracks were connected, and new cars, a new queue area, and a new show building were installed. Announced in April of 2001, The Rocket Rods would not be returning after a long downtime. High expense and unreliability were the blame, but no official reason for their closure was given. Space Mountain has reopened, and Buzz Lightyear's Astro Blasters currently is housed in the space of the previous attraction, Circlevision360.  The Disneyland Monorail underwent extensive refurbs as part of the Finding Nemo Submarine Voyage, and 3 new Mark 6 trains have come online in 2009: Monorail Red, Blue and Purple.

Rumors abound and we may also see the return of such classic attractions as The Peoplemover and the Rocket Jets.
 

Additional Corporate Sponsored Events in Tomorrowland:

The Richfield Show: Sponsored by Richfield Oil, this show had an exhibit and film titled "The World Beneath Us", which detailed the search for oil. They also sponsored the Tomorrowland Autopia. (Chevron currently sponsors the new "Autopia 2000" attraction). Dutch Boy Paints sponsored the "Color Gallery", and Kaiser Aluminum sponsored "Hall of Aluminum Fame". 

From 1956 to 1960, Crane Corporation sponsored the "Bathroom of Tomorrow". This display introduced such items as glass walls, gold fixtures, gold leaf tile, and sunken tubs.
