Charity and social media will unite for the first Tweetathon for Telethon today.
The 10-hour event, between 8am and 6pm, encourages people to use their Twitter accounts to help raise money for the charity.
For each tweet sent to @Bankwest and @Telethon7 with the hashtag #tweetforkids, Bankwest will contribute $1 for Telethon.
If a tweet is sent with a photo of the new Bankwest Place store on Murray Street, Bankwest will donate $5 (one donation per Twitter account).
Bankwest is also using the opportunity to test free Wi-Fi at the new site, so people tweeting photos will not have to use their own data accounts.
Telethon general manager Steve Mummery said Channel 7 personalities including the Sunrise team and Perth's X Factor finalist Johnny Ruffo would use Twitter to encourage followers to take part.
If each of Ruffo's followers were to tweet, Bankwest would have to donate more than $118,000.
In another marriage of technology and social media, Qantas announced a campaign on Friday for people to upload photos for a chance to have their name on the side of one of the airline's planes or be featured in a new commercial.It donated $5 to Mission Australia for everyone who submitted a picture - up to $100,000, which was achieved on the first day.
